Product Description
The HMJ5 is a high dynamic range GaAs FET
mixer. This active FET mixer realizes a typical
third order intercept point of +35 dBm at an LO
drive level of +17 dBm. The HMJ5 comes in a
low cost, J-Lead package. Typical applications

Notes:
1. Test conditions unless otherwise noted: 25 ºC, RF = 905 MHz @ -10 dBm, LO = 900MHz @ +17 dBm, IF = 5 MHz.
2. Measured in a 50-Ohm system with nominal LO drive in a downconverter application only, unless otherwise specified.
3. LO frequency must be separated from IF frequency by a minimum of 2 MHz (i.e., | FLO –FIF
