Strong Radio Frequency Circuit

Iar with a 10.7 MHz input, an audio output, along with provisions for an S-mctcr and AFC. The input of the LM3089 is preceded by a 10-7 MHz ceramic filter which in turn is preceded by a coupie of what appear to be microwave transistors. The first transistor amplifies the 1 GHz signal from the microwave circuit board and passes it on to the second transistor, which is also fed by the 1 GHz second LO, mixing the received signal down to 10.7 MHz see Figure 2 and Photo C , The 1 GHz second local...
