Abstract
Provided is a microwave and millimeter wave transceiver package technology that can unify the transceiver composed of an amplifier, a filter and a mixer into a low temperature co-fired ceramic (LTCC) module package by using an LTCC method utilizing a multilayer dielectric substrate, thereby achieving miniaturization, a loss reduction and moderate price. The transceiver includes a plurality of cavities arrayed in a multilayer substrate, an amplifier and a mixer mounted in the cavities and a filter provided with a strip line between the amplifier and the mixer.
Claims10
A transceiver using a low temperature co-fired ceramic (LTCC) method, comprising:
- a plurality of cavities arrayed in a multilayer substrate;
- an amplifier and a mixer mounted in the cavities;
- and
- a filter having a strip line between the amplifier and the mixer,
- wherein the multilayer substrate includes a lowest ground plane and a highest ground plane, a pad for input/output of a bias on a lowest ground plane, and the lowest ground plane is connected to the highest ground plane through the ground plane of side walls of the multilayer substrate.
