MD-158

Double-Balanced Mixer, 5 - 1500 MHz V 3.00 MD-158 Features Low VSWR Conversion Loss: 6 dB Typical Midband LO-RF Isolation: 35 dB Typical Midband Conversion Loss Flatness: 1.5 dB Typical Impedance: 50 Ohms Nominal Maximum Input Power: 300 mW max. @ 25°C, Derated to 85°C @ 3.2 mW/°C n IF Port Current: 50 mA Max. n MIL-STD-883 Screening Available n n n n n n FP-2 Description Transformers convert to the LO and RF paths to balanced lines connecting a low barrier, Schottky diode ring quad. These transformers help provide excellent isolation between ports. Conversion loss is low. The direct connection of the IF port to the diode quad allows these mixers to be used as phase detectors and bi-phase modulators. Advanced transformer design yields improved VSWR.
