Hybrid Power Amplifier Modules & Custom Design AR RF/Microwave Instrumentation has developed a new line of wideband, hybrid power amplifier modules (HPMs) covering the 6 — 18GHz frequency range. These hybrid modules require only a single DC volt source and are 50ohm cascadable building blocks with output powers up to 37dBm. The six new hybrid power modules have excellent typical gain flatness, noise figure, and low intermodulation distortion. They also feature low spurious signals, excellent linearity, and are 100% load tolerant. These characteristics make the HPMs ideal for many RF applications that require linearity, medium power and wide bandwidth. AR has the capabilities in-house to create custom HPM design solutions with frequencies from DC to 20GHz. The customer can explore infinite possibilities with custom power amplifier modules for each application.

Airbus specification AMD-24C has now been incorporated into the specification ABD0100.1.8. The EMC Partner solution is a plug and play module for the already popular MIG2000-6 test system. The new module (Fx-AMD-24C) generates 2/10µs, 2/50µs, 2/100µs, 2/200µs and 2/400µs impulses. Together with the inductive coupling clamp CN-MIG-BT4, these can be superimposed on to AC or DC power lines either individually or simultaneously. A new de-coupling network, DC-S17CL, is needed to maintain high enough impedance on the line being tested so that the specified impulse reaches the unit under test. For more information, visit Upconverter Supports Transceiver Test Keithley Instruments, Inc. a world leader in advanced electrical test instruments and systems, is offering the Model 2891-IQ Upconverter, which provides comprehensive support for transceiver testing by processing analog I and Q baseband signals for testing a transceiver's transmitter, as well as processing analog I and Q output signals for testing a transceiver's receiver. The Model 2891-IQ converts single-ended baseband analog I and Q signals from a signal generator into differential output signals to provide input signals for testing transceivers with differential baseband I,Q inputs. On the receiver side, it converts the receiver's down-converted differential I and Q signals into a modulated, up-converted signal for receiver performance testing by an RF signal analyzer. It speeds and simplifies designing transceiver test systems because it interfaces easily with both RF transceivers and with Keithley's Series 2900 RF vector signal generators and Series 2800 RF Vector signal analyzers. For more information, visit Anritsu Microwave USB Power SensorsAnritsu is now offering the MA24108A/MA24118A microwave USB power sensors that provide accurate average power measurements from 10MHz to 18GHz over 60dB of dynamic range. Employing a dual path architecture to achieve true-RMS measurement similar to a thermal sensor over the entire frequency and dynamic range, the power sensors can measure CW, multi-tone, and digitally modulated signals used in commercial and aerospace/defense systems. Both sensors can either internally trigger or receive an external trigger signal, allowing them to conduct multi-slot and burst average power measurements of TDD waveforms, typically found in GSM, WiMAX, and TD-SCDMA signals. The MA24108A/MA24118A do not require a separate module for triggering. They have built-in external trigger circuitry with an MCX connector interface to receive triggers from external stimuli. Incorporating a micro-controller, signal conditioning circuitry, ADC, and power meter. The MA24108A has a price of $2,695 and the MA24118A has a price of $2,995.

For more information, visit Westek Smart Fieldmeter Digital Westek's Smart Fieldmeter Digital (SFD) electromagnetic field monitor is a battery-operated instrument/data logger capable of 55 hours measurement operation with primary or rechargeable cells. The standard SFD electromagnetic field monitor is supplied with probes selectable from three isotropic models (0.2MHz to 3GHz; 2MHz to 12.5GHz; 3MHz to 18GHz). Probes are automatically calibrated on insertion. Field measurements can be made in V/m (0.01 to 1000V/m), and W/cm2 (0.02nW/cm2 to 249mW/cm2) on the basis of three-axis isotropic rms observations. The auto zero function operates at regular intervals and is accurate even in very high field strength environments. Measurements can be made on the basis of spatially averaged or time averaged analysis (30ms to 30s, under software control). The monitor uses a data processor with data storage on removable flash memory data storage cards (MMC comp-atible) capable of typically storing data files of 100,000 points with a total capacity of 999 data files. For information, visit High-Power Signal Generators for RF Component TestAeroflex expanded its flexible PXI modular test platform with the addition of two 3020 Series high-power and compact RF signal generators. The 3020 Series are compact, high-precision PXI modular RF signal generators with integrated dual-channel arbitrary waveform generators ideally suited for R&D manufacturing and design verification of RF components and systems. The addition of the 3021C and 3026C extend the output power range of the 3020 Series to +17dBm for frequencies up to 3GHz and 6GHz respectively. Weighing 1kg. (2.2lbs.) and occupying just 3 x 3U PXI slots, the 3021C and the 3026C are the lightest and most compact signal generators to offer output power up to +17dBm. In addition, both of these new signal generators achieve low DC power consumption of less than 50W, which results in lower running costs than conventional instruments. The 3021C RF signal generator has a frequency range of 100kHz — 3GHz, offering the same performance specifications as the 3026C, but with an extended low-end frequency range and a more economical price tag for applications below 3GHz.
