The passive components available in the Bree Engineering custom product lines include a broad range of both performance characteristics and unique applications. Filters cover the 0.1 Mhz to 40 Ghz range in Lowpass, Highpass, Bandpass, Bandstop and Multiplexing. 1% to multi-octave 3dB bandwiths are available. These filters can be configured in a number of formats to realize very simple to highly complex filter schemes. While Bree Engineering specializes in surface mount products these same designs can be packaged in more traditional pin outs and connectorized versions. Bree Engineering is capable of providing distributed element type filters, comblines and interdigitals.

THE FOLLOWING ARE EXAMPLES OF PAST RF FILTER DESIGNS
This Diplexer is an example of the custom RF Filter Diplexers that we are able to design and manufacture at Bree Engineering.
This filter suppresses signals below 1.65 GHz by more than 40 dB, and passes signals from 2.0 GHz to 18.0 GHz with less than 1.0 dB if insertion loss and typically more than 17 dB of return loss in the passband. This filter is available from stock.
This filter passes 1900 MHz to 2185 MHz with 14.0 dB minimum return loss in the passband. The surface mount package size is 1.5 X 0.3 X 0.2 inches. (Other configurations are available.)
These multi-channel switched filter banks cover from 100MHz up to 8 GHz and are now in production. We offer customizable multi-channel, TTL Controlled Switched Filter Banks that use a +5 volt DC bias and a 0V/+5V control logic (3.3vdc optional). Units are available 2 or more channels, and using any of the filters currently manufactured by Bree Engineering, with custom band breaks as required. Typical switching speed is 10 – 200 µsec. Rejection up to 70dBc.
A series of miniature filters includes a surface mount data link transmitter cleanup filter.
Bree Engineering’s 5 section high performance lumped element filter designed into a low profile SMT package.
A series of filters includes a surface mount package with a common input to high pass and low pass filters.
Bree Engineering’s high density surface mount filter featuring gull wing lead pins for input, output and grounding.
This series of bandreject filters far exceeds the applications original needs. The passbands of interest are the cellular at 700 to 894 MHz and the PCS at 1850 to 2000 MHz.
