CV210-3A
Cellular-band Dual-Branch Downconverter
BIAS
CV210-3A: The application circuit can be broken up into three main functions
as denoted in the colored dotted areas above: RF/IF diplexing (blue), IF
amplifier matching (green), and dc biasing (purple).
placeholders for chip components in the circuit schematic so that a common
PCB can be used for all WJ dual-branch converters. Further details are given
in the Application Note located on the website titled “CV2xx Series - PWB
Design Guidelines”.
IF Amplifier Matching:
optimize the performance of the amplifier to the desired IF center
frequency. Since IF bandwidths are typically on the order of 5 to 10%, a
simple two element matching network, in the form of either a high-pass or
low-pass filter structure, is sufficient to match the MMIC IF amplifier over
these narrow bandwidths. Proper component values for other IF center
frequencies can be found in the IF Amplifier Matching Table or by e-mailing

External Diplexer:
incoming RF signal impinges on the switching elements of the
mixer; the interaction with these switches produces a signal at
the IF frequency. The two signals (RF and IF) are directed to
the appropriate ports by the external diplexer. A four-element
diplexer is used in the circuit implementation.
DC biasing:
amplifiers in the converter. R1 sets the operating current for
the last stage of the LO amplifier and is chosen to optimize
the mixer LO drive level. Proper RF chokes and bypass
capacitors are chosen for proper amplifier biasing at the
intended frequency of operation. The “+5 V” dc bias should
be supplied directly from a voltage regulator.
