ABSTRACT:
A broadband driver amplifier module is made using an arrangement of MMICS and microstrip to provide inline rf connectors for the input and output and a small package size. The input and output microstrips incorporate a microstrip portion which is at an angle to the axis of the input connector providing an offset from the axis of the input connector. There is provided at least one MMIC extending from the input microstrip at the offset across the input connector axis and having an output on the other side of the axis. This arrangement provides for an overall zigzag configuration which reduces the axial length of the package while maintaining inline input and output connectors. The invention further includes novel arrangements for MMIC mounting and d.c. blocks used in the amplifier.
