Making History: Advanced System in a Package Technologies Enable Direct RF Conversion

RF data conversion systems are experiencing rapid changes as ADC and DAC performance specifications and form factors, along with new sensor technologies (Rx & Tx), continue to advance. One system level design problem has been consistent throughout—balancing the implementation tradeoffs between the analog and digital circuitry for maximum software/system flexibility (from sensor to the digital processing units’ input/output).

App Note: Crystal Oscillator Based Clean-Up Modules

Modern electronic equipment like Radar, Test and Measurement, Instrumentation, Avionics, require precision frequency sources with low phase noise. Although frequency accuracy and precision can be derived from atomic clocks, low phase noise often is not. NEL Frequency Controls Clean-Up VCXO bridges the gap by offering a complementary low phase noise solution to go along with use of atomic clocks. NEL’s application note “Crystal Oscillator Based Clean-up Modules” addresses improving the phase noise of atomic clocks as well as other types of precision frequency sources.

Understanding Suspended Substrate Stripline Filters

Suspended substrate filter technology uses air cavity construction achieve high Q and avoid the adverse effects of dielectric materials used in traditional stripline construction. The resulting performance gives designers the advantages of wide passbands with low insertion loss and stopband rejection on the order of 100 dB with fast roll-off. This paper reviews the fundamentals of suspended substrate filters, key performance features and the unique manufacturing challenges associated with these useful building blocks for wideband systems.

Automatic Fixture Removal with Copper Mountain Technologies VNA

Automatic Fixture Removal (AFR) is a simple and an accurate way to de-embed a measurement fixture. These fixtures are typically used when measuring Surface Mount Device (SMD) type components to provide an interface from the Vector Network Analyzer (VNA) test port cables to the Device Under Test (DUT). The main challenge when characterizing such components is to completely isolate the actual DUT characteristics from the fixture; which becomes even more challenging at higher frequencies.

TDD ARTICLE_FInal

Due to its flexibility and improvements to spectrum utilization, time division duplex (TDD) is vital to the successful operation of 5G cellular communications networks. TDD implementation requires superior synchronization and precise timing at the transmitter and receiver to avoid latency and timing overlap.

NI AWR DESIGN ENVIRONMENT: Load-Pull Primer for Optimizing PA Performance

Power amplifier (PA) performance under small- and large-signal operating conditions is contingent upon the output impedance match (load). As a result, PA designers must determine the ideal output load for system-driven amplifier requirements such as output power at a given saturated power (compression point), efficiency, and/or linearity.
