... Philips Semiconductors Low-voltage digital IF receiver CIRCUIT DESCRIPTION Mixer The mixer has a single–ended input. The input impedance is 670 in parallel with a 3.0pF cap at 110.52MHz RF. The mixer output can drive a 1500 ceramic filter without any matching required. Oscillator and Buffer The on-board oscillator supplies the signal for the mixer down-conversion. The internally biased transistor can be configured as a Colpitts or Butler overtone crystal oscillator. The transistor’ ...
