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. 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.
3. Assumes the supply voltage = +5 V. OIP3 is measured with ∆f = 1 MHz with IFout = 5 dBm / tone.
4. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies.
5. The maximum junction temperature ensures a minimum MTBF rating of 1 million hours of usage.

(not used in this product)
CV111-1: The application circuit can be broken up into four main
functions as denoted in the colored dotted areas above: RF/IF
diplexing (purple; this is only used with the cellular-band CV
products), 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.
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.
RF / IF Amplifier Matching: The RF amplifier requires a
matching element (C12) for optimal gain and input return loss
performance. 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].
IF and LO Lowpass Filtering (optional): Filtering of unwanted
RF and LO signals are typically performed in the IF chain. This
filtering function may be realized using lumped elements;
placeholders (L9, C21, C22) are provided in the application circuit
to allow for lumped-element filtering to be implemented if desired.
The LO lowpass filter is used only in the cellular-band CV products;
it should not be used for this product. L1 should be loaded with a 0
Ω jumper.
RF Bandpass Filtering: Bandpass filtering is recommended to
achieve the best noise figure performance with the downconverter.
The bandpass filter, implemented with a SAW filter on the
application circuit, allows for the suppression of noise from the
External Diplexer: This is only used with the cellular-band CV
products. The mixer performs the diplexing internally for the
CV111-1; therefore the components shown in the diplexer section
should be loaded as follows: C2 = C14 = 0 Ω.
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.
