A block diagram is contained in Fig. 2. In application the RF input of the device is interfaced through appropriate impedance matching to the first IF signal, which is downlinked from the outdoor unit at typically 950-2150MHz. The RF input preamplifier of the device is designed for low noise figure and for low distortion so eliminating the requirement for RF AGC. The preamplifier also provides gain to the mixer section and back isolation from the local oscillator section. 6.2n H TO DEVICE 0.7p F The output of the preamplifier is fed to the mixer section where the RF signal is mixed with the local oscillator frequency, which is generated by an external oscillator. Signals from the mixer are...
