Our LNA products are being discontinued from August 2021 due to critical component obsolescence.
We have a sufficient components put by to service and maintain existing customer units as required.
(RX ONLY, masthead use requires user to add antenna relays, sequencer & weatherproof enclosure)

We are immensely proud to have been involved with the DSA-10 Fast Radio Bursts project in California, developing and manufacturing the SBA1300/1700. 20 amplifiers feature on the 10 dish system with dual polarization feeds.
Here's some background ... DSA RX report 2016 here DSA-10: A Prototype Array for Localizing Fast Radio Bursts 2019 here DSA-10 is the prototype for a planned 110 dish and eventually a 2000 dish deployment. |
SBA amplifier features ...
Tested PCB or boxed. Very low noise figure, interstage filtering, high stability and excellent input VSWR (>10dB return loss), predictable and consistently high performance in your system without critical LNA NF tuning. Rugged 100mW permissible input power. The simple enclosure mounting uses 2 off 6.5mm sma jack holes.
We are asked from time to time why the SBA VLNA is described as a 'Golden Sample' ? Well the NF, passband and input match are so repeatable in production that we think it gives you the best opportunity to improve your system, without being hampered by thoughts of 'tuning to the VSWR of your antenna', out of channel interference degradation doubts or indeed general stability.
SBA is the rugged VLNA (Very Low Noise Amplifier) of choice for world leading radio astronomy groups, providing stable professional grade performance and repeatability at a reasonable price. Caltech SBA1300/1700 application at Owens Valley Observatory here
