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, J-Lead pack-
age. 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.
