Product Description

The CV111-1A 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 conv ersion,

modulation and demodulation for receivers used in

CDMA/GSM/TDMA, CDMA2000, W-CDMA, GPRS,

and EDGE 2.5G mobile infrastructure technologies for

PCS / DCS 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.

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.

CV111-1A: The application circuit can be broken up into four main

functions as denoted in the colored dotted areas above: RF/IF

diplexing (purple; this is only used with the cellular-band CV

products), amplifier matching (green), filtering (red), and dc biasing

(blue). There are various placeholders for chip components in the

circuit schematic so that a common PCB can be used for all WJ

single-branch converters. Additional placeholders for other optional

functions such as filtering are also included.

RF / IF Amplifier Matching: The RF amplifier requires a shunt

matching element for optimal gain and input return loss performance.

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 provided by emailing to

applications.engineering@wj.com.

RF Bandpass Filtering: Bandpass filtering is recommended to

achieve the best noise figure performance with the downconverter.

The bandpass filter, implemented with a SAW filter on the

application circuit, allows for the suppression of noise from the

image frequency. It is permissible to not use a filter and use a 2 dB

pad with R6, R7, and R16 instead with slightly degraded noise

figure performance.

External Diplexer: This is only used with the cellular-band CV

products. The mixer performs the diplexing internally for the

CV111-1A; therefore the components shown in the diplexer section

should be loaded as follows: C2 = C14 = 0 Ω.

DC biasing: DC bias must be provided for the RF, 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.
