The 6 Best RF operational Amplifiers (2023 reviews)

The hiletgo rf operational amplifier is suitable and reliable and fits well with your daily purpose. This is basically a little MMIC amp like the ones from Mini-circuits. It filters everything instead of amplifying. This is a small signal amplifier which could be used ahead of a receiver or a test instrument like a spectrum analyzer. This one (HiLetgo) looks less "fancy" and has an unshielded chip, so it automatically gets back-drawer status. It is used for a short wave, fm radio, remote control receiver, such as cable tv signal amplifier with low noise rf signal amplification.

Why We Like This:

Works at 12v for full gain
Great low noise amp for your sdr project
Performs superbly with a 9 volt battery
Gain is adjustable through your computer app

Aymario RF operational Amplifier

Buy on Amazon

It's a broadband amplifier with quite a bit of gain and no rf filtering, so if you have any nearby FM broadcast stations, they're going to be amplified too, which can saturate the amplifier, making the amp useless. It is especially suitable for all kinds of radio frequency receiving front-end circuit to extend communication distance.

This amp's noise floor is measured to be 0.6 dB at 900 MHz, so that puts it in the ultra-low-noise category. It has a wide frequency range of 5-3500mhz, and large dynamic range +20dbm@1dbp. It is used for short wave, fm radio, remote control receiver, cable tv signal amplifier, gps satellite navigation, 2.4g bluetooth and wifi receiver rf front-end that need low noise and small signal rf to be amplified too, which can saturate the amplifier, making the amp useless.
