1.9 – 2.7 GHz Dual-Branch Downconverter

Product Features

Product Description

Functional Diagram

The CV221-2A 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 and repeaters. It

provides high dynamic range performance in a low profile

RoHS-compliant/lead-free surface-mount leadless package

that measures 6 x 6 mm square.

IF Amp 1

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.

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 Δf = 1 MHz with RFin = -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 R1 resistor can be modified for the CV221-2A to draw less current. Changing it from 13 to 18Ω is expected to have the converter draw 17mA less current so that the converter will draw about 300mA

typically under LO drive, while degrading the IIP3 performance by 0.5 dB.
