440-520MHz 7.5W 9.6V PORTABLE RADIO
DESCRIPTION
The RA07N4452M is a 7.5-watt RF MOSFET Amplifier Module
for 9.6-volt portable radios that operate in the 440- to 520-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 2.5V (minimum), output power and drain
current increases substantially. The nominal output power
becomes available at 3V (typical) and 3.5V (maximum). At
VGG=3.5V, 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
(IDD0 @ VDD=9.6V, VGG=0V)
• Pout>7.5W @ VDD=9.6V, VGG=3.5V, Pin=20mW
ηT>43% @ Pout=7W (VGG control), VDD=9.6V, Pin=20mW
• Broadband Frequency Range: 440-520MHz
• Low-Power Control Current IGG=1mA (typ) at VGG=3.5V
• Module Size: 30 x 10 x 5.4 mm
• Linear operation is possible by setting the quiescent drain current
with the gate voltage and controlling the output power with the
input power
