Specifications

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

4. Assumes the supply voltage = +5 V. IIP3 is measured with Δf = 1 MHz with RF

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.

Absolute Maximum Rating

Operation of this device above any of these parameters may cause permanent damage.
