... Bias circuitry for bandgap biasing and circuit shutdown With the TH7111 receiver chip, various circuit configurations can be arranged in order to meet a number of different customer requirements. For FM/FSK reception the IF tank used in the phase coincidence demodu- lator can be constituted either by a ceramic resonator tank (optionally with varactor to create an AFC circuit) ...

... IF (IF1) and their images which could be mixed down to the same second IF (IF2) as the desired RF signal (they must be suppressed by the LC filter at IF1 and/or by low-crosstalk design). By configuring the TH7111 for double conversion and using its internal PLL synthesizer with fixed feedback divider ratios (DIV_16) and (DIV_2), four types of down-conversion are possible: low-side injection of LO1 and LO2 (low-low), LO1 low-side and LO2 high-side (low-high), LO1 high-side and LO2 low-side (high-low) or LO1 and LO2 high-side (high-high) ...
