The RA07M3340M is a 7-watt RF MOSFET Amplifier Module for 7.2-volt portable radios that operate in the 330- to 400-MHz range. It features enhancement-mode MOSFET transistors, direct battery connection to the drain, broadband frequency range, low-power control current, and the ability for linear operation.
The RA07M3340M is a 7‑watt RF MOSFET amplifier module designed for 7.2‑V portable radios operating in the 330‑400 MHz band. It uses enhancement‑mode MOSFET transistors and can be driven directly from a battery, with output power controlled by gate voltage or input power.
Key features include a compact 30 × 10 × 5.4 mm package (H46S), low‑power gate control current of 1 mA, and RoHS compliance. The module is intended for non‑linear FM modulation but can also support linear AM modulation when the drain quiescent current is set via gate voltage.
| Frequency Range | 330‑400 MHz |
|---|---|
| Gate Voltage (Vag) Rating | < 3.5 V |
| Input Power (Pin) | 70 mW |
| Gate Current (Igg) | 1 mA (typ) |
| Module Size | 30 × 10 × 5.4 mm |
| Package Code | H46S |
| Total Efficiency | 40 % |
The MOSFET module is sensitive to electro‑static discharge down to 1000 V, so appropriate ESD protection must be used during handling and assembly.
RoHS compliance is shown by the letter “G” placed after the lot marking on the device.
