Radio Frequency Systems
The filters offer a compact and flexible solution for both transmitter mask filtering and digital RF channel combining. The DAB filter range is founded on RFS' world-leading RF combining technology and utilizes a similar platform of components to the company's VHF Band III;digital television combiners. DAB filters can beincorporated within transmitters to provide critical mask filtering of the digital RF signal, in keepingwith global DAB standards. When used as the key components of a balanced DAB combiner, thefilters can achieve both critical transmitter masking and adjacent channel combining simultaneously,eliminating the need for additional filters within the transmitter.

Analog Devices Inc.
It is often beneficial to use a video driver at the output of a video encoder for power savings, line driving, and additional circuit protection. The video driver is typically configured as an active filter, also known as a reconstruction or anti-imaging filter. The purpose of the reconstruction filter is twofold: it blocks the higher frequency components (above the Nyquist frequency) that were introduced into the video signal as part of the digitization process and provides gain to drive the external 75 Ω cable to the video display.

HF-ERF™ Series -
Pole/Zero
The HF-ERF™ is an internally switched 3‑band, low cost, miniature, high performance tunable filter. The HF-ERF™ was designed to have the best insertion loss and Q in the smallest package possible, 2.0” x 2.78” x 0.6”. All HF-ERF™ filters are fully tested and aligned by Pole/Zero for convenience and ease of use. Both SPI and Parallel control interfaces are available in one filter. Modified variants are available upon request.

K&L Microwave
K&L Microwave offers a variety of Tunable Filter Products to satisfy a broad range of filtering applications. Tunable Bandpass and Bandreject filters provide the best solution for pre-tuning the desired signals while rejecting the interfering signals. The method of tuning can be either mechanical via a tuning knob mounted on the front of the filter, or electro-mechanical via an optional remote digital interface such as GPIB, RS-232, RS-422, BCD, ARC171, ARC234, Ethernet, USB or "Thumbwheel" panel mount.

MINI-ERF® Series -
Pole/Zero
The MINI-POLE® Extended Range Series of tunable filters was developed to address applications needing a small, surface mount package with wide tunability. This tunability is accomplished by the use of multiple internal tunable filters along with high performance PIN diode RF band select switches all contained in one housing. The tunable filters are designed to minimize size and power consumption while maintaining high RF power handling and linearity characteristics. Parallel or serial digital interface can be selected by a mode pin for ease of integration into your design.

GEN3-ERF® -
Pole/Zero
The 3rd Generation Mini-ERF is a Reduced SWaP-C, 30 to 520 MHz tunable bandpass filter that features 50mW (typ.) power consumption, 1 Watt CW continuous power handling (7% BW), +40 dBm IIp3 (typ.), low insertion loss, and 4 dB typ. selectivity @ +/-10%, (7% filter). The GEN3-ERF’s are fully tuned and tested by Pole/Zero® for convenience and ease of use.

ERF-5W™ Series (Single & Dual) -
Pole/Zero
The new ERF-5W™ filter takes Pole/Zero’s MINI-ERF® technology to a higher level of RF power handling, with 5W (average) in-band power handling, and covering the entire military tactical radio tuning range of 30-520 MHz in one integrated package. This tunability is accomplished by the use of three poles of selectivity, multiple internal tunable filters along with high performance PIN diode RF band select switches. The tunable filters are designed to minimize size and power consumption, while maintaining high RF power handling and linearity characteristics. Serial control is accomplished via a standard Serial Peripheral Interface (SPI)-based bus.
