High-speed logic devices such as XOR gates and Type-D flip-flops can be used for a surprisingly broad range of circuit functions at microwave- and millimeter-wave frequencies.
A new generation of digitally controlled variable-gain amplifiers (VGAs) features low noise figures and a broad control range to lower cost and simplify the design of cellular base stations.
Advances in circuit and system design and measurement software tools are allowing RF/microwave design engineers to incorporate actual measured results into their design efforts.
The trick is combining self-injection locking with mode-coupling techniques to shave the size, cost, and phase noise from voltage-controlled crystal oscillators (VCXOs).
These reliable switch matrices provide low loss and high isolation through 18 GHz and are supplied with software for simple setup and control with a USB-equipped personal computer.
By employing a unique technique that increases device transconductance, this differential, integrated CMOS LNA offers improved gain and noise-figure performance at millimeter-wave frequencies.
