Avago’s MGA-30x89 series (MGA-30789, MGA-30889, MGA-30989) now covers frequency bands from 40 to 6000MHz and only requires a simple DC biasing match. Moreover, no additional RF matching components are required to achieve wide bandwidth performance. The ease-of-use and extended broadband performance of Avago’s MGA-30x89 series makes these gain blocks an ideal choice for designers of cellular devices, WiMAX wireless base stations, satellite and cable TV set-top boxes, and a variety of other wireless applications that operate within the 40 to 6000MHz frequency range...

The AS1367 is a precise, low noise, high speed, low dropout regulator with adaptive operation. Features included are high ripple rejection and low dropout voltage, a reference voltage source, an error amplifier and a current limiter. The AS1367 provides high speed operation, low power consumption and high efficiency by automatically switching between a light load and a heavy load mode depending upon the output current level. The EN function enables the output to be turned off, while the electric charge at the output capacitor is discharged via the internal auto-discharge resistance, and as a result the VOUT pin quickly returns to the GNDlevel. Furthermore a Bypass Pin is included to reduce noise. The device features integrate short-circuit and over current protection. Under-Voltage lockout prevents erratic operation when the input voltage is slowly decaying. Thermal Protection shuts down the device when die temperature reaches 160°C. This is a useful protection when the device is under sustained short circuit conditions. The device is available in a 8-pin TDFN 2x2 package...

The AS3992 UHF Gen 2 Reader chip is an integrated analog frontend and provides protocol handling for ISO180006c/b 900MHz RFID reader systems. Equipped with multiple built-in programming options, the device is suitable for a wide range of UHF RFID applications. The AS3992 is pin to pin compatible with the previous AS3990/91 IC's. It offers improved receive sensitivity to -86dB, fully programmable Rx DRM filters on chip and pre-distortion. Fully scalable, the AS3992 is ideal for longer range and higher power applications. Offering DRM compliance on chip, combined with improved sensitivity and pre-distortion allows the AS3992 to be the only true world wide shippable IC. The reader configuration is achieved through setting control registers allowing fine tuning of different reader parameters...

The TPS22924C is a fully-integrated load switch with typical ON resistance (rON) of 5.7-mOhms at 3.6-V, four times lower than the nearest competitor. The TPS22924C integrates at least four parts into one to simplify subsystem load management. The high level of integration in an ultra-small 1.4-mm x 0.9-mm chip scale package (CSP) addresses space-constrained, battery-powered applications such as portable industrial and medical equipment, media players, point-of-sale terminals, global positioning systems (GPSs), netbooks/notebooks, and Smartphones...
