詳細(xì)描述, ,The RF6280 is a multi-functional Power Management Unit which is used in conjunction with power amplifiers and designed to be used in 3V handheld systems. The RF6280 consists of a DC-DC converter three 2.85V LDOs and a bias control circuit to adjust the PA bias. The DC-DC Converter is a buck converter that provides high efficiency over a wide output voltage range with minimal ripple. It has a fast response to load and line transients and fast response to program (V,SET,) voltage changes. The converter includes an auto-bypass function which allows the handset to operate at lower battery voltage while helping maintain PA linearity at maximum output power. The converter output voltage is set by a variable control voltage V,SET,. The RF6280 has three individual LDOs which are enabled by a digital two bit logic signal. The three LDO outputs are used for band select in tri-band WCDMA handsets.,特點,Peak Efficiency Up To 96%,High Efficiency Over Various Loads,Transient Response <10,650mA Current Capability,Variable Output Voltage (0V to VBATT),2.5MHz PWM Switching Frequency,Automatic Bypass Mode,Over Temperature Shutdown,Current Limit,Analog Bias Control (Automatic and Buffer),Three Individual Fast Transient 2.85V LDOs,Controls up to 3 UMTS PAs,Small Wafer-Level Chip-Scale Package

詳細(xì)描述, ,The RF5516 provides a complete integrated solution in a single Front-End Module (FEM) for WiFi 802.11a systems. The ultra small form factor and integrated matching minimizes the layout area in the customer's application and greatly reduces the number of external components to only one bypass capacitor for supply decoupling. This simplifies the total Front-End solution by reducing the bill of materials, system footprint, and manufacturability cost. The RF5516 integrates a Power Amplifier (PA), Single Pole Double Throw switch (SP2T), Low Noise Amplifier (LNA), and a power detector coupler for improved accuracy. The device is provided in a 3mm?x?3mm?x?0.5mm, 16-pin package. This module meets or exceeds the RF Front End needs of IEEE 802.11a WiFi RF systems.,特點,Single Supply Voltage 3.0 Vto 4.8V,Integrated 5GHz Amplifier, LNA, and SPT2T Tx/Rx Switch,POUT = 15.5dBm, 11a, OFDM at 3% EVM
