Reject Adjacent Interfering Signals In Agile Signal Environments Reject Adjacent Interfering Signals In Agile Signal Environments

Teledyne Microwave Solutions offers a series of tunable bandpass, and fast-tuned notch filters ideal for tactical communications and other defense applications. These filters are specifically designed to accurately tune a bandpass filter over up to an octave bandwidth, and to protect ESM receivers from high duty cycle frequency agile interference from on board or cohort combat radar systems.

Tuneable High-Q, High Power VHF/UHF Bandpass Filter: CB503 Tuneable High-Q, High Power VHF/UHF Bandpass Filter: CB503

The CB503 tuneable High-Q, high power VHF/UHF bandpass filter is comprised of a three section passive machined combline filter with an input/output coupling structure. This coupling structure enables the filter to be tuned to any central frequency in the range of 160 MHz to 360 MHz while maintaining its high-Q and excellent rejection, insertion loss, and center return loss performance. This filter is ideal for de-confliction filtering, military mobile/mounted VHF/UHF communication systems, and base station antenna filter applications.

Fast Tune Notch Filters Fast Tune Notch Filters

Teledyne Defense & Space (TDS) offers a range of fast tune notch filters (FTNF) that have been designed to protect Electronic Support Measures (ESM) receivers from high duty cycle, frequency agile interference produced by on board (or cohort) combat radar systems. ESM sensors need protection from high-level, long pulse and frequency-agile radars.

YIG Tuned Band-Reject Filters YIG Tuned Band-Reject Filters

The new line of YIG Tuned Band-Reject Filters from Teledyne Microwave Solutions (TMS) covering frequency range of 125MHz to 18GHz, are powered by new patent-pending technology that overcomes long-time design limitations inherent to YIG Band-Reject, or “notch” filters. This TMS product line delivers to customers several major performance advancements that are unparalleled to date in the industry.

Ultra-Miniature UB Series Lumped Element Filters Ultra-Miniature UB Series Lumped Element Filters

The ultra-miniature UB Series of lumped element filters from K&L Microwave are capable of operation in applications with frequencies ranging from 300 to 2500 MHz. These filters are available with 2 to 5 resonant sections, and bandwidths from 5% to 15% for ƒ0 < 1000 MHz, or 10% to 20% bandwidths for ƒ0 ≥ 1000 MHz.

EMI Filters And Capacitors EMI Filters And Capacitors

Knowles Capacitors’ excellence in ceramic materials technology, combined with EMI filter expertise, has enabled Knowles (Syfer brand) to offer an unequalled range of EMI filter products including surface mount filters, panel mount filters, planar arrays, discoidal multilayer capacitors, X2Y integrated passive components, and other filter types for hi-rel applications.

Bandpass Cavity Filter: UF9382 Bandpass Cavity Filter: UF9382

MtronPTI’s UF9382 is a high bandpass cavity filter with less than 1.5 dB passband attenuation designed to operate in applications with temperatures ranging from -40°C to +85°C. The filter features a passband range of 9.820 GHz – 9.970 GHz, and an insertion loss less than 2.2 dB.

Digitally Tunable LC Filter: TF0113 Series Digitally Tunable LC Filter: TF0113 Series

MtronPTI’s TF0113 Series of Digitally Tunable LC Filters are found within Vehicle Adapter Amplifiers (VAA), and can dynamically manage the RF spectrum for clear, secure information, and enhance its safety features. When handheld and manpack radios are plugged into VAAs, they can reach a range of 40 km or more.
