US Patent:

59990597, Dec 7, 1999
Filed:

Jan 2, 1998
Appl. No.:

9/001961
Inventors:

Richard J. Blount - Federal Way WA
Leon M. Underkofler - Blanchard ID
Assignee:

Thomas & Betts International, Inc. - Sparks NV
International Classification:

H03G 330
US Classification:

330289
Abstract:

A broadband amplifier has a microcontroller having tables the entries of which correspond to desired variable slope and gain characteristics of the amplifier. The entries in the tables are derived from known temperature characteristics of a specific amplifier/cable combination; multiple tables are used to support multiple different configurations. The microcontroller retrieves values from the tables based on temperature data supplied thereto via a serial bus; these values are output to digital-to-analog converters which generate slope and gain control signals to control slope and gain compensation circuits in a PIN diode attenuator in the amplifier.
