COMPACT PLLS CUT CURRENT IN PORTABLE SYSTEMS

SYNTHESIZER designers are being seriously challenged by designers of p ortable, handheld wireless systems. These system-level architects want frequency accuracy, but at a low price and with almost no current con sumption. The response from Synergy Microwave Corp. (Paterson, NJ) is the production of the SPLL series of phase-lock-loop (PLL) frequency s ynthesizers. The compact components cover bandwidths to 25 MHz at cell ular frequencies from 700 to 1100 MHz with only 35-mA current consumpt ion.
