Design of a Broadband L-band 160W GaN Power Amplifier Using SMT Packaged Transistors 

by  Plextek RFI & Qorvo The design of a broadband power amplifier for L-band radar and wideband communications applications is described. Using a state-of-the-art Qorvo transistor in a cost-effective SMT plastic package, the amplifier has 160W output power between 1.2GHz and 1.8GHz and a typical efficiency of 55% for the complete connectorized PA. Particular consideration […]

Understanding The Limitations Of Modern Military Radio Testbeds

by JFW Industries, Inc. In the past 10 years, the use of military radios has increased dramatically, and, in turn, so has the need to test those radios. In part, this increase stems from the advent of such military-based communication applications as the land mobile radio system and tactical networks, as well as the introduction […]

RF Power Amplifier Module

Now available with full design support capabilities is a new ultra-wideband power amplifier module from Analog Devices, Inc. The HMC-C582 is a GaAs MMIC pHEMT power amplifier in a miniature, hermetic module with replaceable SMA connectors that operates between 0.01 to 20 GHz. RICHARDSON RFPD (99)

Surface Mount Low Pass Filter

ULP-50+ is a surface mount low pass filter with a passband from DC to 50 MHz. Designed using high Q capacitors and chip inductors, this model provides 1.5 dB passband insertion loss, 1.2:1 passband VSWR, 40 dB stopband rejection, and steep roll-off in the transition. MINI-CIRCUITS (101)

NB-IoT RF Performance Test Solution

The Narrow Band Internet of Things (NB-IoT) RF performance test solution has been selected by RDA Microelectronics to help accelerate its NB-IoT chipset testing. NB-IoT is a narrowband cellular radio technology designed for the IoT by 3GPP. The deep coverage and extremely low power consumption of NB-IoT have created new R&D challenges in RF performance […]

Ultra-Wideband Mixer 

The LTC5553 is a double balanced mixer providing best-in-class matched bandwidth capability from 3 to 20 GHz. It can be used either as an up- or down-converter. The device integrates an LO buffer requiring only 0 dBm input drive, effectively eliminating an external high power LO amplifier circuit. ANALOG DEVICES, INC. (94)

Impedance Matching Pads

Models 851-879-MF4 and 851-879-FM4 are 50 to 75 ohm impedance matching pads that operate from DC to 4 GHz. The RF connector configurations for both models are 50 ohm SMA (male or female) to 75 ohm F (male or female). Insertion loss is 5.7 dB nominal, VSWR is 1.50:1 maximum, input power is 1W average. […]

C-Band Circulator

A new 4-port, ferrite-based, C-band circulator integrates forward and reverse power detectors that operate up to 75W. This circulator also features a detection calibration circuit and a high power beryllium oxide (BeO) termination. For weight reduction, it is housed in a lightweight aluminum body weighing 5 ounces.
