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.
The SMA Receivers Upgrade
Wide IF Band Receiver
300GHz receiver with wide IF range
One of the two SMA wideband 300GHz receiver inserts from ASIAA. This is a new generation receiver with wider IF operation frequency from 4GHz to 12GHz. This receiver has shown fairly flat noise temperature performance between 4 to 12GHz, and the lowest noise contribution of this receiver has approached to 3 times quantum noise. (3hv/k)
