Product Description
The HMJ8 is a high dynamic range GaAs FET mixer.
This active FET mixer realizes a typical third order
intercept point of +37 dBm at an LO drive level of +18
dBm. The HMJ8 comes in a low cost, 18-pin J-Lead
package. Typical applications include frequency up/down
conversion, modulation and demodulation for receivers
and transmitters used in communication systems.
