1Mhz-800Mhz 4W VHF UHF RF Power Amplifier Ham Radio HF FM Transmitter Walkie Talkie Short Wave 868M 915M LORA Helium Miner SDR

1-800mhz 4W HF VHF UHF FM transmitter Broadband RF power Amplifier For Ham Radio Walkie talkie Short wave 868M 915M




Note: The RF power amplifier is a vulnerable part, be sure to connect the input and output and pay attention to the impedance matching and power-on test



VHF UHF RF power amplifier


WORK frequency : 0.5MHz~1000MHz ( Power not less than 4w within1-800M )


Input voltage 15-30V DC


Maximum gain 40dB@25MHz


Typical output power 36dBm (approximately 4w)


1: Support wide voltage input, within the allowable supply voltage range, how the input voltage changes and the output power is still stable

2: Larger heat sink, this module will generate a lot of heat, very hot and very hot, small heat sink will not work

3: The parameters are not false. All parameters are from actual measurement. The lowest frequency of the back-end chip used in this amplifier is 100MHz (official data). When my lowest frequency is 50MHz, the output drops to 23dBm, and the output is negative after 2MHz.
