Telonic Berkeley

Pioneer in Design and Develop
RF Solutions

Telonic Berkeley delivers top level solutions for radiofrequency attenuation and filtering with very high level standard precisions. 

Today, the product line has expanded into a complete series of rotary step, programmable and custom attenuators, as well as a complete filter product line including a broad range of Tunable Bandpass Filters covering from 8 MHz to 4 GHz. 

Services and Capabilities

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. Telonic Berkeley 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.

Telonic Berkeley has a wide portfolio of Attenuators and  Filters.  Do not hesitate to inquire us, our Engineers will be ready to help. Otherwise have a look to our solutions portfolio

Radio Frequency filters and attenuators

Key benefits and features

Tunable filters

Telonic Berkeley offers tunable bandpass filters (8 MHz to 4 GHz) with 1-octave tuning, 1.0% to 10.0% bandwidths, and manual or computer-controlled options. Ideal for noise figure measurements, spurious 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

Tandem attenuators, such as the miniature model 8140, provide a compact solution by combining step units (8121 & 8122) in a single assembly with a single dial and dB readout. They offer precise instrumentation with a full attenuation range in 1 dB steps up to 109 dB, including subminiature versions with a 69 dB range.

Sub miniature & miniature step attenuators

Telonic's step attenuators, available in nine models, cover attenuation ranges from 1 to 100 dB in 1 to 10 dB steps. With compact case designs (1.31" diameter, 1.50" subminiature, and 2.29" miniature), these attenuators conserve panel space, offering high power and precision through Telonic's solid-state resistive elements.

Programmable attenuators

Telonic's coaxial step attenuators blend thick film chip technology with "edge line" conductor theory for cost-effective, precise attenuation in the OEM automatic instruments and system market. The thick film chips enable higher-than-normal power handling in this compact unit.
