Microwave Switch Description

All three Microwave Switch modules provide switching of up to five microwave coaxial switches or channels. The difference between the HP E1368A Microwave Switch, the HP E1369A Microwave Switch Driver, and the HP E1370A Microwave Switch/Attenuator Driver modules are described below:

∙The HP E1368A Microwave Switch is a 3-channel, single-pole, double-throw coaxial switch module. The three coaxial switches provided have excellent electrical characteristics for 502 transmission systems operating from DC to 18 GHz. The module panels are numbered 00, 01, and 02 to indicate the channel number of each coaxial switch installed.

∙The HP E1369A Microwave Switch Driver is identical to the HP E1368A, except the coaxial switches are not installed. The module panel has three cutouts and various mounting holes that allow the user to install up to three 3-port, 4-port, or 5-port, 42Vpk drive level coaxial switches. Drive level voltage can be internal (+5 and +12Vdc) or external (42Vpk). The module panel is numbered 00, 01, and 02 to indicate the channel number of each coaxial switch. Channel 03 and 04 are not labeled on the panel. Up to five coaxial switches can be controlled (e.g. three internal, two external; five external; etc) using the 14-pin connector.

∙The HP E1370A Microwave Switch/Attenuator Driver is identical to the HP E1369A, except the module panel and mounting holes have been modified to allow the user to install one Single-pole, Multi-throw Switch or one Step Attenuator. Because of the size of the switches and the attenuators, the module takes up two B-size slots. Drive level voltage can be internal (+5 and +12Vdc) or external (42Vpk). Up to a Single-pole, Six-throw Switch can be mounted on to the assembly or used externally using the 14-pin connector.
