VeGA Barebones - Ultra Low-Noise Variable Gain Amplifier (VGA) Module for RF & Software Defined Radio (SDR). Highly Linear & Wideband 30MHz-4000MHz Frequency Capability

VeGA is a very high performance, LNA module designed for general purpose SDR applications with two options to adjust the gain of the device.

Each module allows for 3 different power options, but you should only power with one option at any given time! The recommended power input through the SMA output port (for bias-tee capable SDRs like the NESDR SMArTee XTR) is 4.5V-5V DC. Alternatively, if you don't have a bias-tee capable SDR, you can use the external power options--the microUSB port, or DC barrel connector. The recommended external power input is 4.0V-5.5V DC.

Though there is protection circuitry on VeGA for overvoltage conditions--and voltages of up to 12V DC should still work and will not damage the device--it is not recommended for long-term usage. Kindly note that damage resulting from overvoltage conditions would not be covered under the standard 1 year warranty.

Each VeGA module has an EMI shield to protect the sensitive circuitry from external interference and is fully ESD-protected.

VeGA has an RF limiter at the RF input port to protect the amplifier from very high power input signals.
