M8T Datasheet, PDF (1/3 Pages) Tyco Electronics – Load Insensitive Mixer

M8T / M8TC
Load Insensitive Mixer
Features
• LO 0.001 to 3.4 GHz
• RF 0.001 to 3.4 GHz
• IF 0.001 to 2 GHz
• LO Drive +10 dBm (nominal)
• Insensitive To VSWR Mismatch
• High Intercept Point +18 dBm (typ)
Description
The M8T is a termination insensitive mixer, designed for use in
military, wireless and test equipment applications. The design
utilizes Schottky bridge quad diodes, broadband ferrite baluns and
internal loads to provide excellent performance without degrada-
tion due to external VSWR mismatches. Environmental screening
available to MIL-STD-883, MIL-STD-202 or MIL-DTL-28837, con-
sult factory.
