CV211-2A Product Features * * * * * * * * * UMTS/WiMax-band Dual-Branch Downconverter Product Description The CV211-2A is a dual-channel high-linearity downconverter designed to meet the demanding 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. 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. Typical applications include frequency downconversion used in W-CDMA 3G and WiMax mobile base transceiver stations.

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 f = 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 maximum junction temperature ensures a minimum MTTF rating of 1 million hours of usage.

Printed Circuit Board Material: .014" FR-4, 4 layers, .062" total thickness CV211-2A: The application circuit can be broken up into three main functions as denoted in the colored dotted areas above: RF/IF diplexing (blue), IF amplifier matching (green), and dc biasing (purple). There are various placeholders for chip components in the circuit schematic so that a common PCB can be used for all WJ dual-branch converters. Further details are given in the Application Note located on the website titled "CV2xx Series - PWB Design Guidelines". IF Amplifier Matching: The IF amplifier requires matching elements to optimize the performance of the amplifier to the desired IF center frequency. Since IF bandwidths are typically on the order of 5 to 10%, a simple two element matching network, in the form of either a high-pass or low-pass filter structure, is sufficient to match the MMIC IF amplifier over these narrow bandwidths. Proper component values for other IF center frequencies can be found in the IF Amplifier Matching Table or by e-mailing to sjcapplication.engineering@tqs.com. External Diplexer: This is only used with the cellularband CV products. The mixer performs the diplexing internally for the CV211-2A; therefore the components shown in the diplexer section should be not be loaded except for L3, L10, L7, and L11, which should contain a 0 jumper. DC biasing: DC bias must be provided for the LO and IF amplifiers in the converter. R1 sets the operating current for the last stage of the LO amplifier and is chosen to optimize the mixer LO drive level. Proper RF chokes and bypass capacitors are chosen for proper amplifier biasing at the intended frequency of operation. The "+5 V" dc bias should be supplied directly from a voltage regulator.
