Toshiba Introduces New High-Frequency Power Detection IC for Mobile Phones
Utilizes RMS Detection for Transmission Power Control in UMTS, CDMA, WCDMA and LTE Mobile Phones
IRVINE, Calif., Aug. 21, 2012 /PRNewswire/ -- Toshiba America Electronic Components, Inc., (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the introduction of the new TCX4A01WBG, a high-frequency power detection integrated circuit (IC) that uses Root Mean Square (RMS) detection for transmission power control in mobile phones.
The small circuit area of the new chip enables high efficiency operation for power amplifiers, and extends battery life - a key concern in the design of today's mobile phones. Toshiba's TCX4A01WBG features an ultra-small package (WCSP4), operating with only a coupling capacitor and a bypass capacitor.
The new power detection IC from Toshiba can extract a high accuracy detection voltage from even the most complex transmission signals - such as those used for 3G or newer phones - and is also suitable for PA power control. Additionally, the chip gives greater freedom in circuit design, which is especially important at a time when multiple bands and complex transmission signals are present due to an increase in data communication demands.
"Today's mobile phones require high-frequency power detection with a small circuit area. The ability to achieve a long battery life is one of the most pressing issues in the design of mobile phones, and has become a consumer expectation," noted Talayeh Saderi, business development engineer for TAEC. "Because the power amplifier consumes considerable power in a mobile phone, having control for the power amplifier is essential."
Features include:
-- Extracts a high-accuracy detection voltage from even complex modulation
signals
-- Uses Root Mean Square (RMS) detection
-- Single-power operation in the 2.5 to 3.3 V range
-- Low power consumption of 0.95 mW (typ.)
-- Ultra-small package WCSP (0.79 mm x 0.79 mm x 0.5 mm)
-- A small number of peripheral circuit parts: operates with only a
coupling capacitor and a bypass capacitor
-- Suitable for UMTS, CDMA, WCDMA and LTE mobile phone technologies
