RA35H1516M
154-162MHz 40W 12.5V MOBILE RADIO
DESCRIPTION
The RA35H1516M is a 40-watt RF MOSFET Amplifier
Module for 12.5-volt mobile radios that operate in the 154- to
162-MHz range.
The battery can be connected directly to the drain of the
enhancement-mode MOSFET transistors. Without the gate
voltage (V_GG=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). At
V_GG=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
(I_DD≅0 @ V_DD=12.5V, V_GG=0V)
• P_out>40W, η_T>50% @ V_DD=12.5V, V_GG=5V, P_in=50mW
• Low-Power Control Current I_GG=1mA (typ) at V_GG=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
