RA18H1213G - 3 Stage Amp

General Description

The RA18H1213G is a 18-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 1.24- to 1.30-GHz range.

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

Key Features

  • Enhancement-Mode MOSFET Transistors (IDD≅0 @ VDD=12.5V, VGG=0V).
  • Pout>18W, ηT>20% @ VDD=12.5V, VGG=5V, Pin=200mW.
  • Broadband Frequency Range: 1.24-1.30GHz.
  • Low-Power Control Current IGG=1mA (typ) at VGG=5V www. DataSheet4U. com.
  • Module Size: 66 x 21 x 9.88 mm.
  • Linear operation is possible by setting the quiescent drain current with the gate voltage and controlling the output power with the input power 2 3 1 4 5 1 2 3 4 5 RF Input (Pin) Ga.

MITSUBISHI RF MOSFET MODULE ELECTROSTATIC SENSITIVE DEVICE OBSERVE HANDLING PRECAUTIONS RA18H1213G BLOCK DIAGRAM 1.24-1.30GHz 18W 12.5V, 3 Stage Amp. For MOBILE RADIO DESCRIPTION The RA18H1213G is a 18-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 1.24- to 1.30-GHz 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 4.5V (typical) and 5V (maximum).
