The up/down converter modules of the Tri-Band RF repeater were realized for iDEN and CDMA respectively. The Up/Down Converter Module for iDEN is composed of a down converter and up converter from the filter to the PAU input in the down link and up link of repeaters and a digital filter of the variable bandwidth. Besides, the same structure is composed in a pair in order to handle two bands such as a 900M band and a 800M band. The Up/Down converter of the down link was realized as a digital filter through a conversion and A/D conversion from the base station(EBTS) signals inputted through the LNA part to the IF frequency. The up/down converter of the Up Link was made to take a Roll Off characteristic using a SAW filter by converting the RF signal of the terminal inputted through the LNA into the IF frequency(70MHz), differently from the down link. And, Digital filter of the up/down converter module for CDMA converts the analog to digital and transmits it to the FPGA in order to filter out the signal. FPGA has a logic algorithm that can filter out each possible Bandwidth in FA, 1.25MHz, minimum value and it selects when CPU send a command to select the pass band. Digitalized signal goes through the DA converter after filtering the signal in any 65MHz PCS band by digital section. Digital filter guaranties a uniform RF division output and an accurate filtering service band in any Sprint PCS spectrum. Also it provides less spatial limitation when designing the HW for the most complicated pass band combinations. The signals passing through the Up/Down Converter are inputted as a PAU module for iDEN and CDMA respectively, so as to amplify the iDEN signals and CDMA signals to a proper output level, pass through a filter realized with an iDEN frequency band and a CDMA frequency band in one body type, and then be discharged through ANT.

The Up/Down Converter Module for iDEN is composed of a down converter and up converter from the filter to the PAU input in the down link and up link of repeaters and a digital filter of the variable bandwidth. Besides, the same structure is composed in a pair in order to handle two bands such as a 900M band and a 800M band. Up/Down Converter of Down Lind converts EBTS signal input through LNA part to IF frequency(62.5MHz) and embodies Digital Filter as A/D conversion. It takes Roll off nature with digital filter, minimized the impact of other signal by stopping nearby other band and other signal, removes spurious and improves degree of separation. In addition, Up link unlike Down link converts Terminal’s RF signal input through LNA to IF frequency(70MHz) to take roll off nature of SAW Filter, minimizes the impact of other signals by restraining them to remove spurious and to improve degree of separation. And, IF signal at the Digital filter of up/down converter module for CDMA is converted to Digital Domain Signal by A/D Converter and sent to the FPGA. The Signal at the FPGA will be filtered out and sent to the D/A Converter. All process of ADC, DAC and FPGA synchronizes in the 10MHz Reference Clock TCXO in order to promise an accurate.

Ver 1.0 | 21 JULY 2009 User Manual of CDMA RF-Repeater <Fig. 11> Block Diagram for CDMA Digital Filter Up/Down Converter module for iDEN and CDMA suppresses leakage of local signals into the input terminal by inserting a band path filter on the front side of a mixer. The mixer minimizes IMD components of the system by applying elements having characteristics of high IP3 and minimizes influence on the next step by maintaining linearity. The base station(EBTS) signals converted into the IF frequency are recovered into the original frequency through the up converter. Local stage for IF conversion is designed to minimize phase noises in order not to reduce quality(ρ value) of waveform that can take place during the conversion process of signals. RF Block of Down Link Up/Down Converter as Down Link Gain Control Block phase performs AGC and ALC functions to protect devices on over-input of iDEN RF Repeater, and with the need of user it may turn On/Off the functions with automatic compensation function for gains on temperature of system. 5.1.4 MultiplexerMultiplexerMultiplexerMultiplexer This was realized in one body type available in both of an iDEN frequency band and a CDMA frequency band with a filter of cavity type and has only the iDEN frequency band and CDMA frequency band to service inputted to the LNA part after securing isolation between the Down Link and UP Link enough while other bands are removed because, of the base station(EBTS) signals of the iDEN and CDMA received through antenna, only the desired bands are made to pass selectively since it is connected to the donor ANT of repeaters.
