The SMA Receivers Upgrade
The evolution of the SMA receiver configuration: the low-noise amplifier (LNA) upgrade. In 2007, the LNA bandwidth remained in 4-6GHz for first generation receiver. By 2011, the amplifier was upgraded to TTI-CLNA-4080 with 4-8GHz bandwidth, manufacture by a Spanish company. Now, we are using the new amplifier, CITCRYO1-12A, made by California Institute of Technology. This new upgrade increases the receiver bandwidth to 4-12GHz.
