Keysight 44476A Microwave Multiplexer Module, Triple 1-to-2 18GHz, 3mm SMA, SPDT 50 Ohm

• Three dc to 26 GHz microwave switches
• High isolation (>90 dB to 26 GHz)
• Internal 50Ω termination
• SMA terminal connectors

Keysight 44476A is a microwave switch module. Three independent SPDT 50 Ohm coaxial relays with excellent electrical performance from DC to 18GHz. make up the 44476A. For general purpose microwave switching applications, the module can be used to switch separate signal sources for a multi-band receiver/transmitter testing application. The 3-mm SMA connectors on the module edge allow ease of wiring.

42842C Bias Current Test Fixture (Obsolete)

Specs:

• DUT Connection: 2-Terminal
• Bias Voltage Output connector: BNC(f)
• Dimensions (approx.): 213(W) x 173(H) x 235(D) [mm]
• Weight (approx.): 3100g

This test fixture is designed for use with the 42841A. It is connected directly to the bias current output terminals of the 42841A. The following features ensure accurate and safe DC bias measurements:

• Clear plastic cover is for safe measurements
• Opening the cover decreases the voltage generated by back-e.m.f. (electromotive force) to a level below 40 V within 0.1 second
• Heat-sensitive switch prevents DUT from overheating
• Also equipped with DC bias voltage monitoring
• Operating Temperature: 0C to 45C
• DUT Size: Smaller than 60(W) x 50(H) x 60(D) [mm]
