CRO/SAW (coupled-resonator oscillator/surface acoustic wave) resonator-based oscillators are widely used as reference sources in phase-locked loop (PLL) applications, since the technology features very low phase noise at fixed frequencies to beyond 3 GHz. CRO/SAW oscillators are also known for high quality factor (Q) and low phase-noise performance. Unfortunately, CRO/SAW...

RF and microwave multifunction boards are getting more complicated, while development schedules are getting shorter to meet time-to-market requirements. In this evolving development process, there is usually not enough time to test the individual blocks, and the feasibility for full deterministic analysis of the whole board is low, especially...

Simulation software is becoming more widespread in a number of industries, and the field of microwave design is no exception. The ability to create virtual prototypes has enabled designers to not only reduce the lead time on new designs, but also to try out new concepts that would otherwise...

In the fiercely competitive GSM phone terminal market, terminal manufacturers have come to expect solutions that expedite their development and cycle times. Coupled with the new feature-rich handsets with mega-pixel cameras, Bluetooth® technology and multimedia functions, designers are demanding smaller and more integrated modules that consume less board space...

One of the crucial components that limits the bandwidth in a communication system tends to be the circulator that duplexes the transmit and receive circuits from the antenna. A new high-power broadband lumped-element circulator has been developed by Renaissance Electronics Corp. (model number 3A2BA) that operates over a nearly...

The advancement of CMOS technology over the past two decades has had a tremendous impact on shaping the semiconductor industry. It was reported in early 1984 that CMOS was finally starting to have a significant impact on the electronics field and was beginning to gain substantial market share. 1...

Traditional microwave transmitter systems can be simplified by replacing up-converting mixers and associated filters with a vector modulator that directly modulates data onto a carrier signal using orthogonal I and Q control inputs for simultaneous amplitude and phase control. The versatility of the vector modulator allows unlimited modulation control...

Recently, with the rapid development and deployment of wireless communication systems, the miniaturization and performance improvement of wireless communication components have become increasingly necessary. In particular, the miniaturization of a filter, one of the core components in many radio frequency (RF) systems, has become a very important issue. Apart...
