Product Description
The HMJ7 is a high dynamic range GaAs FET mixer.
This active broadband mixer realizes a typical third order
intercept point of +34 dBm at an LO drive level of +21
dBm. The HMJ7 also provides excellent suppression of
spurious intermodulation products, greater than 60 dBc.
The HMJ7 comes in a low cost, 22-pin J-Lead package.
The combination of high dynamic range and spurious
suppression makes the HMJ7 an ideal choice for CATV
headend transmission equipment and other applications
requiring a broadband mixer in the 1000 MHz to 2000
MHz frequency range.

Condition
RF = 1018 MHz @ 0 dBm
1. Test conditions unless otherwise noted: 25 ºC, RF = 1018.75 MHz @ 0 dBm, LO = 21 dBm, IF = 50, 650, 860 MHz in a high-side LO configuration.
2. The 2x1 spur is tested where the IM spur = 2 * RF input – LO, where RF input = 1018.75 MHz @ -5 dBm, LO = 1568.75 & 1668.75 MHz @ 21 dBm, IM spur = output frequency. The IM spur level is
specified in dBc with respect to the desired IF frequency calculated: IF output = LO - RF input.
