About this item
  • A wideband (30MHz-4000MHz), high-performance, general purpose LNA module with a built-in variable attenuator to maximize usability and portability
  • The attenuation can be controlled either with the on-board potentiometer (analog control) or push button array (digital control)
  • Dual amplifier design with adjustable gain (20dB-50dB at 100MHz), low noise figure and low power consumption. Can be powered through bias tee (3.3V-5V), USB, or DC power
  • Made in North America. Full 1 year warranty!
  • NOTE: Some SDRs will require a DC block between the LNA and SDR if utilizing the external power options. For more information review the product page or datasheet: nooelec.com/datasheets/100826
Product description

FOR FULL SPECIFICATIONS AND DETAILS, PLEASE REVIEW THE PRODUCT PAGE AND DATASHEET AT NOOELEC.COM 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 2 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.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
