LINEAR POWER AMPLIFIER 890-915 MHz 12.5 VOLTS INPUT/OUTPUT 50 OHMS POUT = 16 W MIN. GAIN = 42 dB MIN.
DESCRIPTION The STM915-16 is a linear power module designed for 12.5 V applications in GSM Cellular Radio Systems. The STM915-16 uses gold metallized
transistors with diffused emitter ballast resistors for high linearity Class AB operation.
