Making Effective Use of Doherty Architecture
With the evolution of 5G technology, the need for antenna array systems is growing.
This increases the demand for efficient power amplifier implementations to support
high-density setups. Imagine you could get 60% more output power, 50% more bandwidth
and up to 20% efficiency gain per amplifier in a MIMO antenna array setup? Would
you spend time on rethinking your implementation plans?
R&S® ZNA Vector Network Analyzer
Offering outstanding RF characteristics and a unique hardware architecture, the
R&S® ZNA high end vector network analyzer makes demanding measurements easier
than ever. ZNA Vector Network Analyzer
- 10 MHz to 26.5/43.5 GHz
- Up to 170 dB dynamic range
- 4 internal phase-coherent sources
- Spectrum analysis option
- Unique touch-only operation
Measurement of the Phase Difference Between
Many applications require a defined magnitude and phase relation between several
signals, for example, to design a smart antenna array and its distribution network,
or to ensure accurate phase alignment between different transmitter or receiver
chains of T/R modules. Magnitude can be measured with spectrum analyzers or power
meters. For phase measurements, a vector network analyzer is the easiest, fastest
and most accurate instrument This application note shows how to measure the phase
accurately between several signals using vector network analyzers.

Mixer & Frequency Converter Fundamentals
Seminar: October 16th, 2019 - Milpitas, CA
Mixers and converters are key components in all RF and microwave systems. They
are used in wireless communication systems for commercial applications such as Wi-Fi
and cellular networks; as well as radars and complex navigation systems used in
defense and aerospace applications. Mixers are used in receivers to downconvert
high frequency signals captured from antennas; and in transmitters to upconvert
baseband signals to higher frequencies for transmissions. They are a critical component
for determining the overall performance of a system with parameters such as gain,
linearity, dynamic range, and particularly spurious response.
