Linear Technology Corp. announces the LTC3887-1, a dual output synchronous step-down DC/DC controller with I²C-based PMBus interface for digital power system management. The LTC3887-1 differs from the previously released LTC3887 by providing a three-state PWM signal, enabling the use of DrMOS, power blocks or similar power stages. The enhanced feature set includes a 70 ms power-up time and a fast ADC mode that provides an 8 ms update rate for one parameter.
Pasternack introduces a line of bi-directional amplifiers that are used for sending and receiving radio signals in key applications. The new bi-directional RF amplifiers consist of 2 narrow band models that operate in L-Band (1.35 to 1.39 GHz) and S-Band (2.4 to 2.5 GHz). These designs utilize highly linear Class AB LDMOS semiconductor technology. A general purpose broadband model is also featured which covers 30 MHz to 3 GHz and uses Class A GaAs semiconductors.
Richardson RFPD Inc. announced the availability and full design support capabilities for a new 2 W power amplifier from M/A-COM Technology Solutions. The MAAP-011145 is assembled in a 7 mm surface mount, lead-free cavity package with a temperature compensated integrated power detector operating from 17.65 to 19.75 GHz. The circuit provides 25 dB small signal gain, +43 dBm OIP3, 2W P1dB, +34.5 dBm saturated output power, and bias of 1330 mA at 6 V.
Linear Technology Corp. announces the LTC3886, a 60 V input dual output synchronous step-down DC/DC controller with programmable loop compensation and I²C-based PMBus interface. This controller employs a constant-frequency, current-mode architecture with programmable output voltage up to 13.8 V. The LTC3886 is ideal for harsh environments requiring a high input voltage range commonly found in factory automation, industrial, medical, communications and more.
RFMW Ltd. announces design and sales support a high dynamic range, analog controlled, variable gain amplifier (VGA) operating from 0.7 to 2.8 GHz. The Qorvo TQC9074 offers 30 dB of analog controlled gain variation range and an OIP3 of 41.5 dBm. Applications include remote radio heads and small cell infrastructure. The TQC9074 draws 235 mA from a 5 V supply. Users can access each stage of the module for performance enhancements in their design.
Exodus Advanced Comm. announced the release of a new high power ultra broadband solid-state power amplifier: AMP1062 operates over 6 to 18 GHz instantaneous bandwidth with 40 W minimum in CW and 30 W P1dB typical output power using state of the art Class AB GaN devices. AMP1062 features 46 dB of gain and 32 V DC supply voltage at 14 amp maximum current consumption.
KRYTAR Inc. announces the continued expansion of its growing line of directional couplers with a new model offering 6 dB of coupling over the frequency range of 10 to 67 GHz, in a single, compact and lightweight package. The latest addition enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling over a broadband frequency range of 10 to 67 GHz.
Linear Technology announces the LTC5549, a double-balanced mixer that can operate either as an upconverter or downconverter, with a very wide RF frequency range from 2 to 14 GHz. The LTC5549 offers exceptionally high linearity of 24.4 dBm IIP3 at 9 GHz. The LTC5549 enables efficient microwave transmitter and receiver designs with an integrated LO buffer that needs only a 0 dBm drive level, effectively eliminating an external high power LO amplifier circuit.
The RM022020 features Qorvo’s patented Spatium™ combining technology to provide unprecedented performance in a general purpose laboratory bench top amplifier for applications that include lab work, test and measurement, load pull, EMI test, and anechoic chambers and test ranges. It is suitable for use a driver/booster amplifier, enabling more power incident upon the device under test (DUT).
