Product Description
The CV110-2A is a high linearity downconverter
designed to meet the demanding issues for performance,
functionality, and cost goals of current and next
generation mobile infrastructure. 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 downconversion
used in CDMA/GSM/TDMA, CDMA2000, W-CDMA,
and EDGE 2.5G and 3G mobile base transceiver stations
for cellular 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 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 240 ± 18 MHz.
4. Assumes the supply voltage = +5 V. OIP3 is measured with
f
= 1 MHz with IF
out
= 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.
