RA30H1317M1
RF MOSFET MODULE 135-175MHz 30W 12.5V 2 Stage Amp. For MOBILE RADIO
DESCRIPTION
The RA30H1317M1 is a 30-watt RF MOSFET Amplifier
Module for 12.5-volt mobile radios that operate in the 135- to
175-MHz range.
The battery can be connected directly to the drain of the
enhancement-mode MOSFET transistors. The output power and
drain current increase as the gate voltage increases. With a gate
voltage around 3.5V (minimum), output power and drain current
increases substantially. The nominal output power becomes
available at 4V (typical) and 5V (maximum). At VGG=5V, the
typical gate current is 1 mA.
This module is designed for non-linear FM modulation, but may
also be used for linear modulation by setting the drain quiescent
current with the gate voltage and controlling the output power
with the input power.
FEATURES
• Enhancement-Mode MOSFET Transistors
(IDD≅0 @ VDD=12.5V, VGG=0V)
• Pout>30W, ηT>40% @ VDD=12.5V, VGG=5V, Pin=50mW
• Broadband Frequency Range: 135-175MHz
• Low-Power Control Current IGG=1mA (typ) at VGG=5V
• 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
