Description
Power supply decoupling. Nominal supply decoupling consists of a
0.1 μF capacitor to ground in parallel with a 10 pF capacitor to
ground positioned as close to the device as possible.
RF input interface. The input channel is ac-coupled through C6.
C7 provides bypassing for the center tap of the RF input balun.
IF output interface. The open-collector IF output interfaces are
biased through pull-up choke inductors, L1 and L2. T1 is a 4:1
impedance transformer used to provide a single-ended IF output
interface, with C5 providing center-tap bypassing. Remove R21 for
balanced output operation.
LO interface. C17 provides ac coupling for the LOIP local oscillator input.
Bias control. R1 sets the bias point for the internal IF amplifier.
