Toshiba Launches New Power Detection IC for Mobile Phones

Toshiba America Electronic Components (TAEC) declared that it has unveiled a new high-frequency power detection integrated circuit (IC) called TCX4A01WBG that employs Root Mean Square detection for transmission power control in mobile phones.

The chip’s small circuit area provides high efficiency operation for power amplifiers, thereby creating prolonged battery life which is a major criterion in designing current mobile phones. Toshiba's TCX4A01WBG boasts an ultra-small package (WCSP4) that functions with a bypass capacitor and a coupling capacitor.

Toshiba’s new power detection IC can consume high precision detection voltage from complex transmission signals like those being utilized for 3G or latest phones. Additionally, it is ideal for PA power control. The chip provides higher freedom in circuit design, which is critical during the existence of multiple bands and complex transmission signals in response to data communication demands.

Toshiba's TCX4A01WBG features an ultra-small package WCSP (0.79 x 0.79 x 0.5 mm); single-power operation ranging from 2.5 V to 3.3 V; acquires a high-accuracy detection voltage from complex modulation signals; employs Root Mean Square detection; and typical low power consumption of 0.95 mW. It includes fewer peripheral circuit parts and compatible with only a bypass capacitor and a coupling capacitor. It is ideal for WCDMA, UMTS, CDMA, and LTE mobile phone technologies.

Toshiba designs and develops advanced flash memory-based storage solutions, hard disk drives, solid state drives, discrete devices, sophisticated materials, custom SoCs/ASICs, medical tubes, microcontrollers, , imaging products and wireless components for use in tablets, smartphones, cameras, MP3 players, medical devices and automotive electronics.\
