Adjustable Bandwidth Tunable (700MHz-1000MHz)

MFA R&D Tunable - K&L Microwave

Allows passband centered at any frequency over tuning range while adding the capability to vary passband width. Upon input of desired frequency and bandwidth, the filter tunes center frequency and adjusts bandwidth to provide a custom filtering solution on demand. 1dB bandwidth of 5MHz to 20MHz. Suitable for LTE and other test applications.

Tunable Non-Reflective Band-Reject Filter (700MHz-1GHz)

SPCL-00597 - K&L Microwave

This device is placed after the DUT to protect the Spectrum Analyzer from high-power fundamentals and provide harmonic measurements. The non-reflective functionality prevents energy from bouncing back to the DUT and raising the noise floor level.Broadband matching improves dynamic range and reducesmeasurement uncertainty.
