The ADL8150 is a self biased gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), heterojunction bipolar transistor (HBT), low phase noise amplifier that operates from 6 GHz to 14 GHz. The amplifier provides 12 dB of typical signal gain, 18 dBm output power at 1 dB gain compression (OP1dB), and a typical output third-order intercept (OIP3) of 30 dBm. The amplifier requires 74 mA from a 5 V collector supply voltage. The ADL8150 also features inputs and outputs (I/Os) that are internally matched to 50 ?, and facilitates integration into multichip modules (MCMs). Note that throughout the data sheet, multifunction pins, such as RFOUT/VCC, are referred to either by the entire pin name or by a single function of the pin, for example, RFOUT, when only that function is relevant.Applications Military and space Test instrumentation Communications

The UCC3750 Source-Ringer Controller provides a complete control and drive solution for a four quadrant flyback-based ring generator circuit. The IC controls a primary-side switch which is modulated when power transfer is taking place from input to output. It also controls two secondary switches which act as synchronous rectifier switches during positive power flow. These switches are pulse-widt

The ADP1882?/ ADP1883 are versatile current-mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current-limit protection by using a constant on-time, pseudo-fixed frequency with a programmable current-limit, current-control scheme. In addition, these devices offer optimum performance at low duty cycles by using valley current-mode control architecture. This allows the ADP1882 / ADP1883 to drive all N-channel power stages to regulate output voltages as low as 0.8 V.The ADP1883 is the power saving mode (PSM) version of the device and is capable of pulse skipping to maintain output regulation while achieving improved system efficiency at light loads (see the Power Saving Mode (PSM) Version (ADP1883) section for more information).Available in three frequency options (300 kHz, 600 kHz, and 1.0 MHz, plus the PSM option), the ADP1882/ADP1883 are well suited for a wide range of applications. These ICs not only operate from a 2.75 V to 5.5 V bias supply, but they also can accept a power input as high as 20 V.In addition, an internally fixed soft start period is included to limit input in-rush current from the input supply during startup and to provide reverse current protection during soft start for a pre-charged output. The low-side current-sense, current-gain scheme and integration of a boost diode, along with the PSM/forced pulse-width modulation (PWM) option, reduce the external part count and improve efficiency.The ADP1882 / ADP1883 operate over the -40?C to +125?C junction temperature range and are available in a 10-lead MSOP.
