CV110-2A
Cellular-band High Linearity Downconverter
The Communications Edge TM Product Information
Product Features
• High dynamic range downconverter with integrated LO, IF, & RF amps
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 surfacemount 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
[email protected]. 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. OIP3 is measured with Δf = 1 MHz with IFout = 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.
