Since its founding in 1958, and under new ownership since 2009, Telonic Berkeley Corporation, hereafter referred to as Telonic Berkeley or TB, has developed a diversified technology base to meet the stringent quality and performance demands of our RF & Microwave Products & Smoke Metering equipment customers. In addition, Telonic Berkeley is a manufacturer of both standard and custom Frequency (RF) and Microwave components. These products are used in Radar, Electronic Warfare Systems, Telecommunications, Satellites and other applications. Over the years, TB has developed a complete RF Filter line including a broad range of Tunable Filters covering the 8 MHz to 4 GHz frequency band.

Telonic Berkeley’s impressive array of fixed filter types has evolved over the years in responding to the demanding needs of the electronic industry while offering performance parameters tailored specifically to each customer’s unique requirements. To meet customer needs, TB employs proven design elements (Lumped Element, Combline/Cavity, and Tubular) to produce high-quality Passband, Lowpass, Highpass, and Bandstop filters, as well as, Diplexers, Multiplexers, and Filter Banks.

Telonic Berkeley has also provided an extensive product line of precision Rotary Step Attenuators for over twenty-five years. In the late 1960’s, when TB needed a precision Step attenuator for one of their newly designed sweep generators, Telonic Berkeley, the supplier of last resort, provided the performance and dependability required by the instrument engineer.

Telonic Berkeley’s design, manufacturing and sales facilities are presently located at 1080 La Mirada Court, in Vista, California, and comprises approximately 8000 square feet of floor space. TB has made extensive investments in computer-aided design and manufacturing systems, a dedicated IBM-compatible file server engineering network, and state-of-the art test equipment to support design and manufacturing activities.

Tunable filters

Telonic berkeley complete filter product line includes a broad band range of tunable bandpass filters covering from 8 mhz to 4 ghz. Tunables bandpass filters are five-section, iris coupled o,o5db chebychev filters. Typical tuning range of each filter it is typically one (1) octave, with bandwidths of 1,0% to 10,0% andcan be provided as manually tuned, computer controlled or as a multi-octave, computer controlled system. In addition, the ttr tunable bandpass filters are 0,1% reject bandwidth, stub tuned 3.section chebychev filters. Narrow bandwidths and broad passbands make these filters excellent for noisefigure measurements, spurious and harmonic signal evaluation, and emc testing.

Fixed frequency filters

Telonic berkeley filters are known and used worldwide. Telonic berkeley impressive array of fixed filters types has evolved over the years in response to fulfilling the demanding needs of the electronic industries while offering performance parameters tailored to each customer’s unique requirements.

Bench type rotary attenuator

Bench type attenuator are disigned as a discrete instruments for use in electronics lbs. Production or metrology applications such ar intermediate testing or quality assurance. Attenuator can be mounted singly or in pairs like show in beside picture.

Tandem rotary step attenuators

These tandem attenuators are combinations of step units, combined in a single assembly with a single dial and db readout. They permit instrumentation designs calling for higher db ranges with fine step divisions. For example, the miniature model 8140 picture here combines the 8121 & 8122 attenuators to provide a full range of attenuation in 1 db steps to 109 db. Tandem, attenuators are available in the subminiature size, offering attenuation range of 69 db.

Sub miniature & miniature step attenuators

These telonic step attenuators are available in nine different models with attenuation range from 1 to up 100 db in steps of 1 to 10 db. These are two basic case designs, both 1,31” diameter with lengths of 1.50” (subminiature) and 2.29” (miniature). This mechanical configuration reduces panel mounting space to a minimum, and also permits incorporation of these attenuators into many existing designs. All version utilize telonic solid state thick film resistive elements for high power, precision, repeatability, and extensive service life.

Programmable attenuators

Telonic’s line of coaxial step, digitally programmable miniature attenuators combines telonic’s thick film (distributed field) chip concept with the “edge line” conductor theory to provide relatively low-cost, highly accurate attenuator for the “oem” automatic instruments and system market. Nature of thick file chips allows higher than normal power handling capability in this size unit.
