MD-179 Datasheet | Tyco Electronics

Features n Intermodulation Ratio is Insensitive to Port Mismatches n VSWR: <2.0:1 Typical Midband n Isolation: 35 d B Typical Midband n Impedance: 50 Ohms Nominal n Maximum Input Power: 350 m W Max @ 25°C, Derated n n V 3.00 MD-/MDC-179 FP-2 (MD-179) to 85°C @ 3.2 m W/°C LO Power: +24 d Bm Max. MIL-STD-883 Screening Available 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. bined, these features give the mixer its insensitivity to external mismatches, plus superior VSWR.
