Abstract :
A low cost, 920 MHz to 30 MHz downconverter/AGC IF IC of novel topology is described. Implemented in Si bipolar technology, this device provides 85 dB of conversion gain, a 15 dB NF (including the 22 dB loss of an external bandpass filter), a leveled output of 41 dBmV (120 mVrms), with a minimum IM ratio of 40 dB. With a companion RFIC, it forms a DAB receiver.
