COFDM Liner PA 1W 2.5W RF Power Amplifier For Wireless Video Transmitter
Key Features:
- Do not interfere with GPS signals
- High linearity, extremely high reliability. Open circuit and short circuit will not damage the power amplifier
- With surface brushed finish or frosted texture, natural conductive oxidation; made of pure aluminum, featuring excellent heat dissipation and a fully metal shielded structure
- Wide Voltage Range: Power supply voltage is 12 to 18V. This is particularly suitable for professional aerial photography transmitters
- Mini size: 43*26*12mm, Bare board size: 35*18*5mm
- RF connector: SMA or MCX
- Compact design. The plug of the MCX version protrudes only 7mm from the cavity when inserted, facilitating installation
- High gain: greater than 43dB (typical value 45/49dB), facilitating connection with modulators that have weak output signals
- High output power: The nominal digital power of digital TV is 1W, with a shoulder ratio greater than 36dB (typical value 38~41dBc)
- Fixed method: 4 through-hole fixing holes with a diameter of 2.5mm. The nuts are recessed and hidden, and the height of the nuts is lower than the surface of the module

Frequently Asked Questions
Q1. Can you make the RF Power Amplifier to be other frequencies? Output 2W,5W and more?
A: Yes, we can make the Power Amplifier to be other frequencies. The frequency range is from F0+-15MHz, if you need 450MHz as the center frequency, then we make frequency range to be 435~465MHz. And we have different power amplifiers with 1W, 2W, 5W, 10W, 20W, 50W.
