Description:

PRL offers two families of products for switching and gating GHz signals:

Switches/Routers

Switch/scanner modules are designed for switching microwave and sub-nanosecond rise time signals in the 50 Ω environment. For reflective switches the unselected ports are not terminated into 50 Ω. Therefore a signal connected to the unselected port will be reflected. The reflective switch is intended mainly for routing a signal from one port to several destinations where not terminating the unselected port into 50 Ω is desirable. These modules can also be used as a scanners when not terminating the unselected ports is acceptable.

For scanning ECL logic and clock signals, PRL offers absorptive switches. In these modules the unselected ports are terminated into 50 Ω/V_TT. Because V_TT varies by ECL family, there are three different models for NECL, PECL, and LVPECL.

For scanning TTL logic and clock signals with a sampling scope PRL offers attenuating switches. In these modules the all ports are terminated into 50 Ω and the selected port is attenuated by 14 dB for compatibility with most sampling scopes.

Switch/router modules are available with BNC or SMA I/O connectors and with rotary or toggle switches for manual output selection, plus TTL/CMOS compatible control input pins for remote control.

Logic Gates

For ECL logic and clock signals PRL also offers logic gates. These modules can be used for signal gating, logic conversion, and signal multiplexing, with switching speeds equivalent to the incoming data rates.

Units are housed in an extruded aluminum enclosure and supplied with a +8.5 V AC/DC adapter.

Product Selection Guide:

* Maximum bandwidth is for SMA versions only. See specifications for BNC models' performance.
