Manually Controlled Tunable Filter

The 5CTB-4000/6000-5-N/N is a manually controlled tunable filter covering 4000 to 6000 MHz. With a 3 dB bandwidth of 5% of the tuned center frequency and 50 dB rejection at 3.5 times that value, this filter achieves the low insertion loss of 1.0 dB maximum. K&L MICROWAVE (11)

Surface Mount Highpass Filters

A new family of miniature highpass filters has cutoff frequencies of 6 to 18 GHz. The filters guarantee rejection of 45 dB at 1/2 the 3 dB cutoff frequency and insertion loss of 2.5 dB maximum. The surface mount package measures 0.44 x 0.24 x 0.16”. K&L MICROWAVE   (10)

Band 5 Wireless Notch Filter

A new Band 5 wireless notch filter has been developed to protect the 800 MHz Public Safety Band from LTE Band 27 interference and emissions. The high Q design of part WSN-00418 provides minimal insertion loss in the two passbands (0.5 dB max. from 817 to 824 MHz, 1.25 dB max. from 862 to 863 […]

Digitally-Tuned Bandpass Filter

Today’s 4G wireless communication systems with carrier aggregation are predominantly using LTE signals modulated over several bandwidths, typically 5, 10, 15, 20 and 40 MHz. Signals generally span from 700 to 6000 MHz. Filtering is often required to reduce harmonics and improve dynamic range when testing LTE products. To replace the large number of fixed […]

Digitally Controlled Tunable Filters

Tunable filters covering ranges up to 8 GHz are now available. The filters provide high Q tunable solutions for many of today’s higher frequency applications using 5-section coaxial cavity construction based on theoretical Chebyshev designs. Available tuning ranges include 2 to 4 GHz, 4 to 6 GHz, and 6 to 8 GHz. Typical bandwidth options […]

Bandpass/Bandstop Diplexer

The WSD-01039 bandpass/bandstop diplexer is designed for Band 7 uplink spurious measurement testing. The diplexer’s bandpass features 0.5 dB insertion loss in the passband of 2500 to 2570 MHz, while the bandstop achieves 40 dB rejection in the same band. The design and performance provide a bandpass filter with a good match in the stopband […]
