1. Specifications when using the application specific circuit (shown on page 3) with a low side LO = 0 dBm in a downconverting application over the operating case temperature range.
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 applications.engineering@wj.com.
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 80 ± 6 MHz.
4. Assumes the supply voltage = +5 V. OIP3 is measured with Δf = 1 MHz with IFout = 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 MTTF rating of 1 million hours of usage.

RF / IF Diplexer
CV110-1A: The application circuit can be broken up into four main
functions as denoted in the colored dotted areas above: RF/IF
diplexing (purple), amplifier matching (green), filtering (red), and dc
biasing (blue). There are various placeholders for chip components in
the circuit schematic so that a common PCB can be used for all WJ
single-branch converters. Additional placeholders for other optional
functions such as filtering are also included.
implemented with a SAW filter on the application circuit, allows for
the suppression of noise from the image frequency. It is permissible
to not use a filter and use a 2 dB pad with R6, R7, and R16 instead
with slightly degraded noise figure performance. Standard WJ
evaluation boards will have the 2 dB pad in place.
External Diplexer: In a downconversion application, the incoming
RF signal impinges on the switching elements of the mixer; the
interaction with these switches produces a signal at the IF frequency.
RF / IF Amplifier Matching: The RF amplifier requires a shunt
matching element for optimal gain and input return loss performance. The two signals (RF and IF) are directed to the appropriate ports by
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
applications.engineering@wj.com.
the external diplexer. A four-element diplexer is used in the circuit
implementation (L8 and C2 are not used). Pin 5 contains the IF
signal and allows the signal to be transferred to pin 25 for the
convenience of PCB layouts.
DC biasing: DC bias must be provided for the RF, 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.
RF Bandpass Filtering: Bandpass filtering is recommended to
reject the image frequencies and achieve the best noise figure
performance with the downconverter.
The bandpass filter,
