Atec Agilent-44478B User Manual

Agilent 44478A/B Dual 1x4 RF Multiplexer Module
(1.3GHz, 50 Ohm)

Data Sheet

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

- Insertion loss less than 1.9dB at 1.3GHz

The 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 1.3 GHz.
High channel isolation (>55 dB at 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
50/75Ω SMB-type resistive termination
onto the on-board male SMB connectors
provided for each channel.
