Filters

Deliver industry-leading in-band insertion loss as low as 0.11 dB and are available in multiple topologies, including lumped element, cavity, SAW, suspended substrate, ceramic, printed, and glass. These high-Q, low-loss filters offer some of the best performance in the industry.

Available in surface-mount and connectorized models, provide insertion loss as low as 0.13 dB. Our extensive library of more than 2,000 high-Q lowpass designs is available across multiple topologies, including lumped element, cavity, SAW, suspended substrate, ceramic, printed, and glass.

In-band insertion loss as low as 0.15 dB and offer some of the best performance in the industry. Our library of high-rejection, high-Q highpass filter designs is available across a wide range of architectures, including lumped element, cavity, SAW, suspended substrate, ceramic, printed, and glass.

Low-loss band-reject (notch) filters provide in-band rejection as high as 80 dB. We offers wide range of high-Q, high-rejection notch filter designs across multiple architectures, including lumped element, cavity, SAW, suspended substrate, ceramic, printed, and glass.

Low Insertion Diplexers and Triplexers are essential for many of today’s defense platforms and modern wireless environments that require spectral fidelity.  Low Insertion Loss Diplexers and Triplexers (1 dB) help Receivers to detect and process low power targets as well as discern targets of interest in an interference heavy environment. 

Spectrum Control’s revolutionary ultra-miniature glass filter designs offer a unique blend of full customization and low insertion loss at an affordable price, and are available in bandpass, lowpass, and highpass configurations. These low-loss miniature glass filters provide industry-leading rejection up to 65 dB in an ultra-compact package.

Spectrum Control’s high-power, low-loss SAW filters deliver insertion loss as low as 1.5 dB while handling continuous input power levels up to 36 dBm (CW), and feature exceptional group delay, low loss, and high power handling. These low-loss SAW filter designs provide industry-leading rejection up to 60 dB in an ultra-compact package.

Spectrum Control’s low-loss ceramic filters deliver exceptional insertion loss as low as 1.3 dB and are available in bandpass, highpass, diplexer, triplexer, and multiplexer configurations. These low-loss ceramic filters provide industry-leading rejection up to 65 dB in an ultra-compact package.

Spectrum Control’s compact Switch Filter Banks deliver fast switching speeds in an exceptionally small housing, with switching as low as 0.1 µs, isolation up to 80 dB, and crossover drift as low as ±0.105 MHz/°C. Spectrum’s miniature Switch Filter Banks also include integrated drivers in an ultra-compact design with heights as low as 0.30”.

Configurable amplified GPS filters deliver low-noise performance as low as 1.6 dB with gain options up to 45 dB and support L1, L2, and L5 output frequencies. A single ceramic filter or a pair of diplexed 3-pole ceramic filters selects only the desired GPS signals while the low-noise gain stage preserves overall receiver sensitivity.
