Tunable Oscillators Cover Multiple Bands

These novel tunable oscillators produce more than one frequency band, making it possible to reduce the number of oscillators required in multiple-band designs.

Visitors to the two IMS booths (Nos. 404 and 405) for Synergy Microwave Corp. will find that it is now possible to cover two frequency bands with one oscillator. The firm’s new line of reconfigurable concurrent oscillators (RCOs), as detailed in the Cover Feature of the May 2013 issue of Microwaves & RF, are capable of generating signals for different communications bands concurrently, available for use as needed. For example, a single RCO could serve multiple-frequency-band applications in wireless local area networks (WLANs), such as 2.40 to 2.50 GHz and 5.15 to 5.85 GHz, saving the cost of separate oscillators. Without sacrificing spectral performance, such as harmonic levels and phase noise, these new RCOs represent significantly reduced size and power consumption at the application level compared to separate voltage-controlled oscillators (VCOs), giving engineers a new starting strategy for many radio designs.
