HMJ5
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 include frequency up/down conversion,
modulation and demodulation for receivers and
transmitters used in communications systems.

Notes:
1. RF = 905 MHz (-10 dBm) LO 900 (+17 dB) IF = 5 at 25°C.
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., |F
LO
- FIF| ≥ 2 MHz).
