Product Features
Applications
Specifications
Test conditions unless otherwise noted:
1. Performance is with the use of an application specific circuit (shown on page 4) with a low-side LO at +17 dBm in a downconverting application at 25° C.
2. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies.
3. IIP3 is measured with f = 1 MHz with RF
4. The return loss is measured after the diplexer which splits the RF and IF signals from the mixer. Details of the diplexing circuit is shown on page 4.
Absolute Maximum Rating
5. Operation of this device above any of these parameters may cause permanent damage.
6. Total sum of the LO and RF port power should not exceed +23 dBm.

circuit does not require any external baluns or bias
elements.
Typical applications include frequency up/down
conversion,
receivers and transmitters used in
next generation RFID technologies such as EPC, ISO,
ETSI, and ANSI. Their small size makes them ideal for
PCMCIA applications.
