Product Features
Specifications
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
3. Assumes the supply voltage = +5 V. OIP3 is measured with f = 1 MHz with IF
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.

The CV111-1 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.
