TX interstage filters
The TX filters reject the spurious signals generated in the upconversion
mixer. They also reject the local, image and IF signal leakage and RX
band noise.
2nd TX buffer
The TX buffer is a bipolar transistor amplifier. It amplifies the TX signal
coming from the first interstage filter.
