Product Description
The CV111-1A is a high linearity downconverter designed
to meet the demanding issues for performance,
functionality, and cost goals of current and next generation
mobile infrastructure basestations. It provides high
dynamic range performance in a low profile surface-mount
leadless package that measures 6 x 6 mm square.
Functionality includes RF amplification, frequency
conversion and IF amplification, while an integrated LO
driver amplifier powers the passive mixer. The MCM is
implemented with reliable and mature GaAs MESFET
and InGaP HBT technology.
Typical applications include frequency down conversion,
modulation and demodulation for receivers used in
CDMA/GSM/TDMA, CDMA2000, W-CDMA, GPRS,
and EDGE 2.5G mobile infrastructure technologies for
PCS / DCS frequency bands.

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 can be found in the IF Amplifier Matching Table or by e-mailing to sjcapps@tqs.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 240 ± 18 MHz.
4. Assumes the supply voltage = +5 V. OIP3 is measured with f = 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. L-R Isolation is referenced to an LO injection of 0 dBm. The L-R performance shown also includes the isolation due to an external SAW filter between the RF amplifier and mixer.
7. The maximum junction temperature ensures a minimum MTTF rating of 1 million hours of usage.

CV111-1A: 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.
RF / IF Amplifier Matching: The RF amplifier requires a shunt
matching element 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 found in the IF Amplifier Matching
Table or by e-mailing to sjcapps@tqs.com.
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
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.
External Diplexer: This is only used with the cellular-band CV
products. The mixer performs the diplexing internally for the
CV111-1A; therefore the components shown in the diplexer section
should be loaded as follows: C2 = C14 = 0 .
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.
