Tower top amplifiers

700MHz-800MHz
Filtronic’s TTA systems are fully compliant with the most stringent public safety RF specifications. The amplifiers have excellent system flatness across the passband and low system noise figure while retaining linearity and out-of-band rejection. This provides optimum inbound coverage and dependable performance in mission-critical applications.

Transceivers

2MHz-110GHz
Filtronic have expertise in developing high performance transceivers across a full range of frequency bands. We have particular expertise in mmWave where we have developed the world’s first 40Gbps stratosphere-to-ground link and the worlds first 10Gbps transceiver applied in trackside to train demonstration links.

Combline filters

100MHz-20GHz
Combline filters can be designed to have bandwidths of 1% to 50% of the centre frequency. Centre frequencies in the range of 100MHz to 20GHz are possible with stopbands extending to 5 times f0 . Wider stopbands are achievable with appropriate resonator loading.

Lumped element filters

1MHz-20GHz
Lumped element technology is commonly used in applications where small size is required, especially at lower frequencies where transmission line devices might be excessively large. Both narrowband and broadband designs are available in high pass, low pass, band pass, band stop and multiplexer form.

Suspended substrate filters

500MHz to 26GHz
Suspended Substrate Stripline (SSS) is traditionally a printed circuit technology that can be used for both broadband and narrowband filters.

Thin film filters

3GHz - 114GHz
Surface mountable thin film filters are available in band pass, band stop, high pass and low pass configurations.

Small cell filters

<6GHz
With the lower power of small cell products, the main drivers to a successful product are compact size, low weight and both high performance and efficiency. The filter has a significant impact on all of these drivers, so it is important to consider these in the technology and design approach of the filters. ‍
