Agilent / HP / Keysight 44478A
44478A Dual 1x4 RF Multiplexer Module (1.3GHz, 50 Ohm)
This Multiplexer Module is an ideal choice for broadband switching of high frequency or fast pulse signals.
Dual 1 to 4 multiplexers provide bi-directional switching of signals from DC to 1.3GHz.
High channel isolation (>55dB at 1GHz) assures quality dynamic range measurements using spectrum, network, or distortion analyzers.
Each 1 to 4 multiplexer consists of seven relays in a "tree" structure, which provides high isolation and low VSWR (voltage standing wave ratio).
All the connectors on the module's edge are female BNC for ease of wiring.
Off channels can be terminated in resistors to maintain proper operation of DUT circuitry.
Simply plug a 50ohms SMB type resistive termination onto the on board male SMB connector provided for each channel.
