Anritsu Designs G-Band Frequency Tripler for
Broadband Instrumentation with AWR Software
Key Challenges
Broadband frequency sources are required to extend the
frequency range of broadband microwave and mmWave
test equipment for applications such as 5G new radio
(NR) communications, automotive radar, and security
(detection) applications.
In some broadband systems, nonlinear transmission line
(NLTL)-based multipliers and receivers have been used to
extend the frequency ranges. In one example, NLTL
distributed harmonic generators (DHGs) can be used to
extend the continuous wave (CW) source from 54GHz to
110/145GHz. However, their required input drive level
must be approximately +24dBm to minimize conversion
loss (and maximize output power) of the desired
harmonic output tone.
For even higher frequency coverage (e.g., to 220GHz),
achieving these drive levels becomes more challenging.
Amplifiers that have P1dB = +24dBm in the range of
45-75GHz to drive a DHG do not exist. In addition,
unwanted harmonics must be filtered at the DHG's
output. Overcoming these challenges requires a multi-
plier with lower required input drive power, broadband
operation, and a balanced structure to naturally suppress
the second harmonic (Figure 1).
