The new 50P-1857, programmable attenuator from JFW Industries, offers solid-state reliability and superior broadband performance. With an operating frequency range of 200 to 6000 MHz, it is ideal for today's wideband variable attenuator requirements including VHF/UHF, LTE and WiMax testing applications. This 50-Ohm device has a dynamic range of 0 to 95 dB in 1 dB steps and is guaranteed monotonic across its entire bandwidth. It is rated to handle up to +20 dBm of RF input power with minimal compression and as high as +25 dBm without damage. The VSWR is a maximum of 2.0:1, or greater than 9.54 dB of return loss. The 50P-1857 also changes attenuation settings quickly with an impressive 300 nanosecond switching speed. The seven-bit attenuator is controlled via seven TTL lines (TTL High turns pads ON, TTL Low turns pads OFF) and it requires a +5 Volt DC supply. SMA female connectors are standard on the input and output, but other connector configurations may also be available upon request.
These specifications, along with a compact and rugged package design, have instantly made the 50P-1857 the new flagship of JFW's attenuator line and spawned several other new model based on its design. In addition to the 0-95 by 1 dB-model described above, other attenuation ranges are available. They include a 0 to 63 dB in 1 dB step version and a 0 to 31.5 dB attenuator with 0.5 dB resolution. And, for applications where it is not possible to maintain uninterrupted TTL control signals, JFW also offers a digitally latching solution.
Building on this assortment of innovative programmable attenuators, JFW Industries continues to expand its line of RF and microwave test equipment by launching a brand new family of programmable attenuator assemblies for automated testing applications. The family begins with the basic 50PA-516; a plug and play RF test solution consisting of two 50P-1857 programmable attenuators (on independent RF paths) integrated with a single Ethernet/RS-232 network interface for remote control, a front-panel interface for manual control (via sixteen-button keypad with three-line display), and a universally adaptable AC power supply (100 to 240 Volts AC @ 47-63 Hz). This complete testing solution allows the user to instantly automate the variable attenuation stage of the test process, dramatically reducing total test time. Computer control offers the user a variety of programming options.
