HP 44478B
1.3 GHz 75 Ohm Max
HP 44478B Product Details
The Agilent 44478A/B 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 (>55 dB @ 1 GHz) 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 50/75 Ohm SMB type resistive termination onto the on-board male SMB
connector provided for each channel.

- Switching up to 1A, 24W or 24VA
