PRL-854-RM, RF Switches & Scanners

Basic Lab Tools > RF Switches & Scanners > PRL-854-RM

Note: The PRL-854-RM replaces the PRL-854 in all applications, as the newer model now provides both manual and remote control in one unit.

Applications:

• Switching GHz/Sub-Nanosecond Rise-Time Signals
• GHz Signal Routing and Scanning

Features:

• DC to 2.5 GHz Usable Frequency Range
• Up to 1.75 GHz 3 dB bandwidth
• Z₀ =50 Ω
• Typical 1.65 dB Insertion loss and 46 dB Isolation @ 1.25 GHz
• 6 ms Switching Time
• BNC or SMA I/O Connectors
• Manual or Remote Control
• Modules include AC/DC Adapters

Description:

The PRL-854-RM is a 1 x 4, DC coupled signal router designed for 50 Ω I/O applications. The usable frequency band extends from DC to over 2.5 GHz. A signal connected to input D can be routed to output Q1, Q2, Q3 or Q4. It can also be used as a Reflective Scanner in the reverse direction, in that signals connected to the Q inputs can be scanned one at a time at the D output. Because signals connected to the non-selected ports are not terminated, these signals will be reflected, hence the term reflective scanner.

The PRL-854-RM-BNC has BNC I/O connectors, and the PRL-854-RM-SMA has SMA I/O connectors. Each model is provided with a 4-position rotary switch for manual channel selection and four LEDs for channel identification. All models also have 2 x 2 stick pins (pulled up to +5V via 4.99 kΩ resistors) for remote TTL/CMOS logic control inputs. The pin designations and truth tables for the logic inputs are shown in the following table. When the rotary switch is set to the fully clockwise position the logic inputs are left open. A0 and A1 are both high, and channel Q4 is selected. Jumpers or remote inputs may be used to pull the pins low.

0 V ≤ L ≤ 0.4 V; 2 V ≤ H ≤ 5 V 

The PRL-854-RM is housed in a 1.3-in. x 2.9-in. x 2.9-in. aluminum extrusion and is provided with a ±8.5 V AC/DC adaptor. If mounting is desired, a pair of 35001420 mounting brackets can accommodate two PRL modules of the same length. A number of PRL modules can also share a single ±8.5 V AC/DC adaptor using the PRL-730 voltage distribution module. Please see the Accessories Section for more detail.
