General Description
The HMC616LP3(E) is a GaAs PHEMT MMIC Low Noise Amplifi er that is ideal for Cellular/3G and LTE/WiMAX/4G basestation front-end receivers operating between 175 and 660 MHz. The amplifi er has been optimized to provide 0.5 dB noise fi gure, 24 dB gain and +37 dBm output IP3 from a single supply of +5V. Input and output return losses are excellent with minimal external matching and bias decoupling components. The HMC616LP3(E) shares the same package and pinout with the HMC617-LP3(E) and HMC618LP3(E) LNAs. The HMC616LP3(E) can be biased with +3V to +5V and features an externally adjustable supply current which allows the designer to tailor the linearity performance of the LNA for each application.

Features
*Low Noise Figure: 0.5 dB
*High Gain: 24 dB
*High Output IP3: +37 dBm
*Single Supply: +3V to +5V
*50 Ohm Matched Input/Output
*16 Lead 3x3mm QFN Package: 9 mm2

Typical Applications
The HMC616LP3(E) is ideal for:
*Cellular/3G and LTE/WiMAX/4G
*BTS & Infrastructure
*Repeaters and Femtocells
*Public Safety Radio
*DAB Receivers

General Description
The AAT2153 SwitchReg is a 2.5A step-down converter with an input voltage range of 2.7V to 5.5V and an adjustable output voltage from 0.6V to VIN. The 1.4MHz switching frequency enables the use of small external components. The small footprint and high efficiency make the AAT2153 an ideal choice for portable applications.
The AAT2153 delivers 2.5A maximum output current while consuming only 42μA of no-load quiescent current. Ultra-low RDS(ON) integrated MOSFETs and 100% duty cycle operation make the AAT2153 an ideal choice for high output voltage, high current applications which require a low dropout threshold.
The AAT2153 provides excellent transient response and high output accuracy across the operating range. No external compensation components are required.
The AAT2153 maintains high efficiency throughout the load range. The AAT2153’s unique architecture produces reduced ripple and spectral noise. Over-temperature and short-circuit protection safeguard the AAT2153 and system components from damage.
The AAT2153 is available in a Pb-free, space-saving 16-pin 3x3mm QFN package. The product is rated over an operating temperature range of -40°C to +85°C.
