DESCRIPTION

The RA13H8891MB is a 13-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 880- to 915-MHz range. The battery can be connected directly to the drain of the enhancement-mode MOSFET transistors. Without the gate voltage (VGG=0V), only a small leakage current flows into the drain and the RF input signal attenuates up to 60 dB. The output power and drain current increase as the gate voltage increases. With a gate voltage around 4V (minimum), output power and drain current increases substantially.

FEATURES

• Enhancement-Mode MOSFET Transistors (IDD0 @ VDD=12.5V, VGG=0V)

• Pout>13W, T>35 @ VDD=12.5V, VGG=5V, Pin=1mW

• Broadband Frequency Range: 880-915MHz

• Low-Power Control Current IGG=1mA (typ) at VGG=5V

• Module Size: 60.5 x 14 x 6.4 mm

• Linear operation is possible by setting the quiescent drain current with the gate voltage and controlling the output power with the input power
