Product Description
The CV211-1A is a dual-channel high-linearity down-
converter designed to meet the demanding 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.
It is ideally suited for high dynamic range receiver front
ends using diversity receive channels. Functionality
includes 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 PCS/DCS 2.5G and 3G mobile base transceiver
stations.

1. Specifications when using the application specific circuit (shown on page 3) with a low side LO = 0 dBm and IF = 240 MHz 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 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. IIP3 is measured with
Δ
f
= 1 MHz with RF
= -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.
