Product Description
The AG403-86 is a general-purpose buffer amplifier that offers high dynamic range in a low-cost surface-mount package. At 900 MHz, the AG403-86 typically provides 20.5 dB gain, +31.5 dBm OIP3, and +18 dBm P1dB. The device combines dependable performance with consistent quality to maintain MTTF values exceeding 100 years at mounting temperatures of +85 qC & is housed in a SOT-86 industry-standard SMT lead-free/green/RoHS-compliant package.
The AG403-86 consists of Darlington pair amplifiers using the high reliability InGaP/GaAs HBT process technology and only requires DC-blocking capacitors, a bias resistor, and an inductive RF choke for operation.
The broadband MMIC amplifier can be directly applied to various current and next generation wireless technologies such as GPRS, GSM, CDMA, and W-CDMA. In addition, the AG403-86 will work for other various applications within the DC to 6 GHz frequency range such as CATV and fixed wireless.

GENERAL DESCRIPTION
The W25X10 (1M-bit), W25X20 (2M-bit), W25X40 (4M-bit) and W25X80 (8M-bit) Serial Flash memories provide a storage solution for systems with limited space, pins and power. The 25X series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code download applications as well as storing voice, text and data. The devices operate on a single 2.7V to 3.6V power supply with current consumption as low as 5mA active and 1μA for power-down. All devices are offered in space-saving packages.
The W25X10/20/40/80 array is organized into 512/1024/2048/4096 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time using the Page Program instruction. Pages can be erased in groups of 16 (sector erase), groups of 256 (block erase) or the entire chip (chip erase). The W25X10/20/40/80 has 32/64/128/256 erasable sectors and 2/4/8/16 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. (See figure 2.)
The W25X10/20/40/80 supports the standard Serial Peripheral Interface (SPI), and a high performance dual output SPI using four pins: Serial Clock, Chip Select, Serial Data I/O and Serial Data Out. SPI clock frequencies of up to 75MHz are supported allowing equivalent clock rates of 150MHz when using the Fast Read Dual Output instruction. These transfer rates are comparable to those of 8 and 16-bit Parallel Flash memories.
A Hold pin, Write Protect pin and programmable write protect, with top or bottom array control features, provide further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device identification.
