Product Description

The CV111-3A 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, CDMA2000, W-CDMA / IMT2000, GPRS, and

EDGE 2.5G mobile infrastructure technologies for

UMTS 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 80 MHz, the specifications are valid from 80 ± 6 MHz.

4. Assumes the supply voltage = +5 V. OIP3 is measured with

Δf = 1 MHz with IF

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.
