Design of LTCC-based ultra-wideband transmitter SiP using CMOS impulse generator

In this paper, a low-cost, compact form factor UWB impulse transmitter module is presented for impulse radio communication and radar. It consists of an impulse generator on chip, a compact UWB band pass filter (BPF) for impulse shaping, an amplifier in package, and a printed planar UWB antenna on board. The small BPF which has a low insertion loss is manufactured using low temperature cofired ceramic (LTCC) process. The performance of designed UWB transmitter is measured with UWB antenna in common communication environment. Measured results show that the designed UWB transmitter can be successfully used for the application of high precision UWB sensors between 3.1 GHz and 9GHz.
