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. 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 鹵7.5% bandwidth. ie. with a center frequency of 80 MHz, the specifications are valid from 80 鹵 6 MHz.
3. Assumes the supply voltage = +5 V. OIP3 is measured with
螖f
= 1 MHz with IF
out
= 5 dBm / tone.
4. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies.
5. The maximum junction temperature ensures a minimum MTBF rating of 1 million hours of usage.
