Amplifier Module for 260-GHz Band Using Quartz Waveguide Transitions

The development of high-performance, low-noise amplifiers has applications for future earth
science and planetary instruments with low power and volume.
Packaging of MMIC LNA (monolithic
microwave integrated circuit low-noise
amplifier) chips at frequencies over 200
GHz has always been problematic due to
the high loss in the transition between
the MMIC chip and the waveguide medium
in which the chip will typically be
used. In addition, above 200 GHz, wirebond
inductance between the LNA and
the waveguide can severely limit the RF
matching and bandwidth of the final
waveguide amplifier module.
