| Frequency Range | 66 – 88 MHz |
|---|---|
| Output Power (typical) | 7 W |
| Drain Voltage (Vop) | 7.2 V |
| Gate Voltage (Vag) range | 0 – 5 V |
| Input Power (Pin) | 30 mW (typ) |
| Total Efficiency | 45 % |
| Package Size | 30 × 10 × 5.4 mm |
| Control Current (gate) | 1 mA (typ) |
| Heat‑sink flatness requirement | < 50 µm |
| Mounting screw torque | 1.8 – 3.0 kgf·cm |
The mounting screws should be tightened to a torque of 1.8 to 3.0 kgf·cm.
The module is sensitive to ESD voltages down to 1000 V and requires appropriate precautions.
The heat‑sink surface must be flatter than 50 µm to avoid cracking the ceramic substrate.
For long‑term reliability the module case temperature should be kept below 90 °C (60 °C under standard conditions).
