CV110-2A

Cellular-band High Linearity Downconverter

Product Features

with integrated LO, IF, & RF amps

PCS/UMTS versions

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.

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.
