Battery Powered Compact and Lightweight RTD THz Oscillator Module

In this work a compact and handheld single resonant tunneling diode (RTD) oscillator module is presented. This module is powered by a standard CR2032 coin cell battery, eliminating the need for an external power supply. The system is build by a stack of two FR4-boards; one consisting of the bias related components and the other used for the RTD integration. With this package a Tx module operating at a frequency of 329.76 GHz with an output power of around 39 µW is shown. The overall system has a dimension of around 3.1 cm x 3.3 cm x 2.45 cm (LxWxH) without housing. For mechanical protection a 3D printed plastic housing is fabricated, resulting in a module dimension of around 8.6 cm x 6.1 cm x 3.8 cm (LxWxH).
