| (R) STM351-2 RF POWER MODULE WIRELESS LOCAL LOOP APPLICATIONS .LI .325.20 .I .P .GAI PRELIMINARY DATA NEAR POWER AMPLIFIER 3 51 MHz VOLTS N PUT/OUTPUT 50 OHMS OU T = 1.0 WAV G (2.0 W PEP) N = 21 dB CASE STYLE H170 DESCRIPTION The STM351-2 module is designed to be used as a linear RF Power Amplifier for WLL or other fixed radio a ccess subscriber applications. This particular model is one of several in design covering the 300-5 00 MHz freque ncy range in individual bandwidths of 25 MHz each. Band splits and corresponding part numbers for all bands are as follows: STM326-2 STM351-2 STM376-2 STM401-2 STM426-2 STM451-2 STM476-2 STM500-2 300-326 MHz 325-351 MHz 350-376 MHz 375-401 400-426 425-451 450-476 475-500 MHz MHz MHz MHz MHz PROTOTYPES AVAILABLE ORDER CODE STM351-2 BRANDING STM351-2 PIN CONNECTION 1. 2. 3. 4.
