Description
The unique design of the termination insensitive mixer (TIM) enables it to apply high reverse voltage to diodes during their "off" phase, in the LO cycle. This allows for higher power level performance with minimum distortion. In addition the TIM has internal loads that provide a good match and also absorb mixer generated LO frequency terms. Combined, these features give the mixer its insensitivity to external mismatches, plus superior VSWR.

Isolation
1. All specifications apply when operated at +7 dBm available LO power with 50 Ohm source and load impedance. 2. For IF Frequencies of 5 - 300 MHz and RF of 10 dBm or less. 3. For MDC-179, add 1.0 dB to conversion loss. This product contains elements protected by United States Patent Number 4,224,572.
