RA45H4045MR - 3 Stage Amp

Description

The RA45H4045MR is a 45-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 400- to 450-MHz range.

The battery can be connected directly to the drain of the enhancement-mode MOSFET transistors.

Features

  • Enhancement-Mode MOSFET Transistors (IDD≅0 @ VDD=12.5V, VGG=0V).
  • Pout>45W, ηT>35% @ VDD=12.5V, VGG=5V, Pin=50mW.
  • Broadband Frequency Range: 400-450MHz.
  • Low-Power Control Current IGG=1mA (typ) at VGG=5V.
  • Module Size: 66 x 21 x 9.88 mm.

For MOBILE RADIO DESCRIPTION The RA45H4045MR is a 45-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 400- to 450-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. The nominal output power becomes available at 4.
