Product Description
The HMJ7-1 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 HMJ7-1 also provides excellent suppression of
spurious intermodulation products, greater than 67 dBc,
meeting
DOCSIS2
and
requirements. The HMJ7-1 is a specially screened
version of the HMJ7 mixer meeting all of the
performance requirements of the HMJ7 with 21 dBm LO
power, but also meeting the suppression requirements for
intermodulation products at a 24 dBm LO power level.
The HMJ7-1 comes in a low cost, 22-pin J-Lead package.
The combination of high dynamic range and spurious
suppression makes the HMJ7-1 an ideal choice for
CATV headend transmission equipment and other
applications requiring a broadband mixer in the 1000
MHz to 2000 MHz frequency range.

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 = 1090 MHz @ -14 dBm, LO = 1190 to 2090 MHz @ 24 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.
