1. Specifications when using the application specific circuit (shown on page 3) with a low side LO = 0 dBm in a downconverting application at 25° C.
2. IF matching components affect the center IF frequency. Proper component values for other IF center frequencies than shown can be provided by emailing to [email protected]
3. The IF bandwidth of the converter is defined as 15% around any center frequency in its operating IF frequency range. The bandwidth is determined with external components. Specifications are valid around
the total ±7.5% bandwidth. ie. with a center frequency of 240 MHz, the specifications are valid from 240 ± 18 MHz.
4. Assumes the supply voltage = +5 V. IIP3 is measured with ∆f = 1 MHz with RFin = -5 dBm / tone.
5. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies.
6. The maximum junction temperature ensures a minimum MTBF rating of 1 million hours of usage.

* The 2nd branch includes another mixer and IF amplifier, which increases the total current consumption
of the MCM to be 380 mA.
Printed Circuit Board Material:
.014” FR-4, 4 layers, .062” total thickness
CV211-1: 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). There are
various 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”.
External Diplexer: This is only used with the cellular-band CV
products. The mixer performs the diplexing internally for the
CV211-1; therefore the components shown in the diplexer section
should be not be loaded except for L3, L10, L7, and L11, which
should contain a 0 Ω jumper.
IF Amplifier Matching: The IF amplifier requires matching
elements to 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 provided by
emailing to [email protected]
DC biasing: DC bias must be provided for the LO and IF 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.
