Abstract:
1. A wide-band driver amplifier module, comprising: a housing having a cavity; a coaxial r.f. input, having a first axis, arranged on a first wall of said housing; a coaxial r.f. output arranged on a second wall of said housing opposite said first wall; a first microstrip section arranged in said cavity and including a first d.c. block, said first microstrip section including a first portion, connected to said r.f. input and extending in a first direction substantially parallel to said first axis, and a second portion extending at an acute angle to said first direction, thereby defining a first offset from said first axis; a second microstrip section arranged in said cavity and including a second d.c. block and choke coil, said second microstrip section including a third portion, connected to said r.f. output and extending in a third direction substantially parallel to said first axis, and a fourth portion extending in a fourth direction having an acute angle to said third direction, thereby defining a second offset from said first axis opposite said first offset; and at least a first MMIC arranged in said cavity and extending in a direction substantially perpendicular to a second direction across said first axis from said first offset, said at least a first MMIC being connected at a first end to said second portion of said first microstrip and having a second end electrically connected to said fourth portion of said second microstrip.
