Transceiver Assembly (Horizontal) (Unit 2 A1 A3 A2) The Ranger-X5 transmitter employs an X-band solid-state amplifier as the stable, power device.  Mounted within the saddle of the radar pedestal are the transceiver assembly subsystems.  The SIDPOL®  model  has  two  units—one  Horizontal  and  one  Vertical  (see  paragraph  Error! Reference source not found.).  The Transceiver Assembly houses: •  500 Watt Power Amplifier (Unit 2 A1 A2 A1) •  RF Up/Down Converter (UDC) / Transmitter Control Assembly (Unit 2 A1 A2 A2) •  Transceiver Power Supply (Unit 2 A1A2 A3) •  Temperature Humidity Sensor (Unit 2 A1 A2 A4) •  Cross Guide Coupler (Unit 2 A1 A2 DC1) •  3-Port Circulator (Unit 2 A1 A2 HY1) •  TR Limiter (Unit 2 A2 V1) The Transmitter Control Assembly includes an RF coupler that allows the burst signal to pass through  the  down-conversion  network  for  sampling  by  the  IQ2-IFD  Intermediate  Frequency Digitizer  (digital  receiver).    In  order  for  pulse  compression  algorithms to  approach  theoretical performance, the transmit signal waveforms must be known and used by the matched filter during the received signal processing stage. The Power Amplifier is a compact 500W solid-state power amplifier (SSPA) housed within the Transmitter  Assembly.    The  Transmitter  Control  Assembly  incorporates  other  radar  front-end components (LNA, RF Amplifier, Signal Generator).  Utilizing pulse widths of up to 100µs, the Transceiver Assembly allows the Ranger-X5 Radar to achieve sensitivity levels comparable to that of a 250kW transmitter with a 1µs pulse (assuming 100:1 pulse compression ratio).     Figure 41. Horizontal Transceiver Assembly (135895-100)

The Ranger-X5 is capable of producing waveforms with duty cycles up to 15% and pulse widths up to 100-µsec utilizing pulse compression technology. The Transmitter Control Unit (Unit 2 A1 A2 A2) provides the control and trigger signals necessary for amplification within the Power Amplifier.   The Transmitter Assembly is comprised of a series of six (6) 100W Solid-State Power Amplifiers and a power combiner providing a minimum of 500 watts of power at the output of the power amplifier.

TECHNICAL DOCUMENTATION  PROTECTING PEOPLE AND ASSETS®  DATE: 27 MARCH 2017 | VERSION: 1.8 51 RANGER®-X5 RADAR SYSTEM (MOBILE) FUNCTIONAL OVERVIEW AND THEORY OF OPERATION EEC® | COMPANY PROPRIETARY  2.1.4.2.2.  Horizontal UDC / Transmitter Control (Unit 2 A1 A3 A2 A2) The Ranger-X5 combines the up and down conversion subsystem into a single unit.  The UDC translates  information  between  the  intermediate  frequency  (IF)  and  X-band  operating frequencies.    It  utilizes  low-noise  amplifiers  (LNA),  RF  Amplifiers,  IF  Amplifiers,  a  Frequency Multiplier (on Horizontal Assembly Only), and a Signal Generator (on Horizontal Assembly Only).  The frequency multiplier and signal generator also provide signals for the Vertical Channel.     Figure 43. UDC / Transmitter Control Assembly (135898-100) – Horizontal  The IQ2-IFD (Unit 2 A1 A3 A1 A1) generates the waveform at the IF frequency of 60MHz that drives the shape of the waveform for the UDC.  The Signal Generator (Unit 2 A1 A3 A2 A2 A6) provides  the  RF  Frequency  and  bandwidth  of  the  transmit  frequency.    The  waveform  and frequency mix in the Image Reject mixer before and route to the RF Amplifier (Unit 2 A1 A3 A2 A2  A1).   From  the  RF  Amplifier, the  RF  signal  (waveform  and  frequency)  route  to  the  500W Power Amplifier  (Unit  2  A1  A3  A2  A1)  for  final  amplification  and  pulse  transmission  into  the waveguide system.   The UDC is a breakthrough in achieving excellent performance of image rejection (without narrow band filters  in the module  or  multiple conversion states),  TR  isolation,  and  phase  noise  in  an integrated module.  This UDC design combines a very simple conversion structure and image-rejection mixer technology, which achieves strong image rejection performance without onboard filters  or  multiple  stages  of  conversion.    This  technology  also  helps  reduce  complexity  and minimize space requirements.  The shielded RF enclosure helps to achieve the required level of TR isolation.

LNA, X-Band (Unit 2 A1 A3 A2 A2 A1) (See Figure 44, Point 6) - (CA910-259L) The LNA is a solid-state device to amplify the very weak return signal with a minimal contribution to the overall noise figure of the receiver.  The primary characteristic of an LNA is the noise figure, a measure of how much the LNA degrades the signal-to-noise ratio of the received signal.  Other important characteristics of the LNA are linearity (measured in P1dB or third order intercept), the survivable input power, and the DC dissipation.

It  has  low  phase  noise,  fast  100  microsecond switching time, and fine 100 Hz frequency resolution.  It requires no additional DC supply voltage and has features such as phase continuous linear frequency sweeping, internal/external 10 MHz reference, and optional pulse modulation.     Figure 45.

This  isolation safeguards the receiver components from  a mismatch  occurring  which  may  damage  the  ceramic  output  window.    The  third  port  (port  3) provides a connection point for the TR Limiter (Unit 2 A1 A3 A2 V1) to protect the critical low power receiver components from the higher power of the transmit signal.

TR Limiter (Unit 2 A1 A3 A2 V1) The Ranger-X5 radar system has a Transmit/Receive (TR) Limiter that contain a small amount of  tritium (see  Volume 1,  Section  4,  Vendor Documentation).    The  TR  Limiter  protects the sensitive  receiver  components  from  the  high-energy  burst  of  the  transmit  RF  burst.   The  TR Limiter is a passive device.     Figure 50. TR Limiter (NWLIM8896-57)   The  receiver  protector  tubes  are  individually  sealed  units  and  normal  handling  does  not present any radioactive problems.  The manufacture of TR Limiters complies with 49 CFR 173.422.  The TR Limiters are parts in compliance with 29 CFR 1910.1200.  The TR Limiters are classified as “electron tubes” in compliance with 10 CFR 30.15 (a) (8).  See Volume 1, Section 4, Vendor Documentation for the Material Safety Data Sheet (MSDS), which includes information about special care and disposal of the TR Limiter.     2.1.4.3.

Fluid Pump Assembly (Unit 2 A1 A3 A4) The Transceiver Systems operate at a very high temperature.  Simple “air cooling” techniques found in other radar systems are not sufficient for extracting heat away from the Transmitter.  To enhance and improve the cooling capability, EEC employs a Liquid Cooling Assembly to remove excess heat from the Transceiver units.  The Liquid Cooling Assembly consists of a Weatherized Liquid  Cooler  utilizing  a  Peltier  device  and  a  Fluid  Pump  Assembly.    The  liquid  is  standard automotive  antifreeze  (Ethylene Glycol,  Propylene  Glycol  or  Glycerol)  that  can  be  purchased worldwide at any automotive parts supplier.   The Fluid Pump Assembly moves the liquid through the cooling system.  The Weatherized Liquid Cooler unit (See paragraph Error! Reference source not found.) acts as the heat exchanger.   Figure 52.
