  • TELONIC BERKELEY FIXED FREQUENCY FILTERS

    A world leading manufacturer of RF andmicrowave components, Telonic Berkeley has a uniqueapproach in the manufacture of filters: To offer anunlimited number of filter models in the widest selectionof filter types, that can be ordered easily by the cus-tomer. As an example, this catalog contains over 20types of filters from 10 MHz to 12GHz. Complementingthis impressive array of filter types is the most completeassortment of GUARANTEED electrical and mechanicaldesign data ever published.

    GUARANTEED Filter Design and Specifying Data These conservative and comprehensive performancedata include the effects of time, temperature, shockand vibration, and for the first time permit you toestablish guaranteed performance specifications forcustom filters in the field.

  • ORIENTATION1. Bandpass data in this catalog is presented as a function

    of 3 dB bandwidths and all curves are normalized to thenominal 3 dB bandwidth.

    2. Lowpass data in this catalog is presented in terms of theVSWR cutoff frequency.

    3. In general, insertion loss is inversely proportional to physical size. To reduce insertion loss for a fixed set ofparameters, generally size must increase.

    TO SELECT BANDPASS FILTERS:(Refer to Fig. 1)

    1. Determine frequencies to be passed. ( B to C ) From ____ MHz to ____ MHz.

    2. Estimate 3 dB BW if different from 1. above, _____ MHz.3. Calculate nominal center frequency A; (Arithmetic mean

    of B & C ) ________ MHz.

    4. Calculate % BW:

    5. Determine frequencies to be rejected D, _______ MHzE, _________ MHz.

    6. Determine amount of attenuation required at frequenciesto be rejected, _________dB.

    7. Determine maximum allowable insertion loss at point A,________ dB.

    8. Calculate BW+ and BW which will be used in later calculations.

    9. Refer to Filter Selection Guide ( pg. 4-5 ) and write down theseries names of the products which:

    a) Operate in the passband frequency range desired.b) Have the percentage bandwidth desired.c) Perform the bandpass function desired.

    10. Turn to pages indicated by types selected and complete calculations to determine:

    a) Number of sections required to perform filteringfunction adequately.

    b) Filter series required for insertion loss or size considerations.

    TO SELECT LOWPASS FILTERS:(Refer to Fig. 2 )1. Determine VSWR cutoff frequency: A _________ MHz.2. Determine frequency where attenuation is required B

    _________ MHz.3. Calculate relative frequency as ratio of frequency to be

    attenuated to frequency to be passed:

    4. Determine attenuation level, ________dB.5. Determine maximum insertion loss allowable, ________dB.6. Refer to pages 9, 10 and 11 for proper filter selection.

  • HOW TO ORDERSignificant specifications and specific instructions should beincluded in your order whenever you desire special options orfeatures.

    Filters may be ordered by (A) standard model numbers that can easily be derived by following the ordering instructionsin each filter section of this catalog or (B) by sending your specific requirements to Telonic Berkeley.

    WHERE TO ORDERIn the United States and Canada your order may be placedthrough our local representative or placed directly with the factory:

    TELONIC BERKELEYP.O. Box 277 Laguna Beach, California 92652

    TECHNICAL DATATelonic Berkeley filters are 100% inspected to verify that all elec-trical and mechanical specifications are met. Written test datais provided on 10% of units shipped, or ten units, whichever isgreater. This test data is recorded for performance at room tem-perature only. All units are, however, exposed to temperaturesin excess of rated limits to ensure that they meet and exceedpublished specifications.

    Test data covering an entire lot of filters ordered is available atan additional charge. Data recorded at temperature extremesmay also be provided at extra cost. Telonic Berkeley would bepleased to quote our customers specific test data requirements,and to supply such data as specified by purchase order.

    TECHNICAL ASSISTANCETelonic Berkeley is represented throughout the world by a qualified staff of field engineers and representatives. They areavailable to supply you, without obligation, with technical data,literature, application engineering and assistance in selecting,specifying and ordering Telonic filters and instruments.
