GSM900 and DCS1800/PCS1900 Dual-Band, Low-Noise Amplifiers

General Description The MAX2651/MAX2652/MAX2653 silicon germanium (SiGe), low-noise amplifiers (LNAs) are intended for use in GSM900, DCS1800, and PCS1900 band wireless handsets. The MAX2651/MAX2652 consist of two LNAs, one optimized for the GSM900 band and the other optimized for the DCS1800/PCS

Low-voltage avalanche regulator double diodes

DESCRIPTION The PLVA2600A series consists of two high performance voltage regulator diodes with common anodes, in small SOT23 plastic SMD packages. The series consists of PLVA2650A to PLVA2668A. FEATURES • Very low dynamic impedance at low currents: approximately 1⁄20 of conventional series •

Vertical deflection circuit

DESCRIPTION The TDA2653A is a monolithic integrated circuit for vertical deflection in large screen colour television receivers. The circuit incorporates the following functions: • Oscillator; switch capability for 50 Hz/60 Hz operation • Synchronization circuit • Blanking pulse
