RF & MICROWAVE TRANSISTORS HF SSB APPLICATIONS

DESCRIPTION The SD1729 is a Class AB 28 V epitaxial silicon NPN planar transistor designed primarily for SSB communications. This device utilizes emitter ballasting to achieve extreme ruggedness under severe operating conditions. ■ OPTIMIZED FOR SSB ■ 30 MHz ■ 28 VOLTS ■ IMD −30 dB ■ COMMON

ECB and LCD Display Bias Supply with Accurate Output Voltage and Temperature Compensation

General Description The MAX1729 micropower step-up/step-down DC-DC converter is ideally suited for electrically controlled birefringence (ECB) and liquid-crystal-display (LCD) bias supply generation. It provides step-up/step-down voltage conversion and reduces output ripple by using a step-up DC-
