MD-160 Termination-Insensitive Mixer, 1 - 1500 MHz Features n n n n n n V 3.00 RH-3 Third Order Intermodulation Ratio is Insensitive to Port Mismatches Conversion Loss: 7 dB Typical Midband VSWR: Typically Less than 1.5:1 @ Midband Impedance: 50 Ohms Nominal Maximum Input Power: 350 mW max. @ 25°C, Derated to 85°C @ 3.5 mW/°C 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. Combined, these features give the mixer its insensitivity to external mismatches, plus superior VSWR.
