K&L has developed and is now shipping an LTE/WiFi testing solution digitally-controlled filtering system that can tune a bandpass filter anywhere in the 700 MHz to 6000 MHz range with continuously adjustable bandwidth. View latest video to see in operation.
Tuning Range: 700 MHz - 1000 MHz
Harmonic Output: 1400 MHz - 4000 MHz (X2-X3-X4)
Input/Output Return Loss: -14 dB
Rejection: 40 dB (BW) = 10 MHz and 3 dB (BW) = 20 MHz
IP3: +100 dBm; Power Handling: 50 W CW
Allows passband centered at any frequency over tuning range while adding the capability to vary passband width. Upon input of desired frequency and bandwidth, tunes center frequency and adjusts bandwidth to provide a custom filtering solution on demand. Suitable for LTE and other test applications. The LTE/WiFi Test Box is the latest addition to this product family.
Bandpass Introduced on Filter Wizard in May 2015
