Member: 6245 Status: Offline Thanks Meter: 0 | Quatation from Service Manual: – The SUMMA includes: – An AGC amplifier for the receiver – A receiver mixer for the 13 MHz down conversion – PLLs for the UHF and VHF synthesizers – IQ–modulators for the transmitter – A power control circuit for the transmitter The power amplifiers (PAs) are MMIC technology (Monolithic Microwave Integrated Circuit). They include three amplifier stages with input, interstage and output matching. I think cause in that. I'll try to change Summa |
