Forward on the importance of quality PDK Tools for RF BAW Filter Design by Colin Field, Supplier Business Manager at RFMW Hardware designers face a perpetual challenge in the RF industry: to create solutions that are smaller, more powerful, and more capable than previous generations of equipment. While high-performance integrated radio front ends and high-speed digital technologies have historically borne the burden of industry demands, the electromagnetic spectrum in which such radios operate is becoming increasingly congested, heightening the need for high-performance, small-form-factor RF filtering. Significant progress has been made, particularly in sub-3GHz bands where SAW technology offers standard solutions…
What made you select Qorvo’s QPA0017 25W Ku-Band GaN Power Amplifier? How does it differentiate from others/what value does it offer? Qorvo recently introduced the QPA0017, a Ku-Band power amplifier in a compact 7.5 x 6 mm SMT package. The device targets the 13.75 to 14.5 GHz satcom band, providing 12.5 Watts of linear power with third-order intermodulation distortion products of 25 dBc. The QPA0017 can deliver up to 25 Watts of saturated output power with 35% power-added efficiency. For small-signal operation, gain is 30 dB. Additionally, the QPA0017 offers an extended operating frequency range of 12.75 to 15.35 GHz,…
What made you feature the Qorvo 1200V SiC Power Modules? How does these products differ from others and what value do they offer? Qorvo’s first SiC module products are housed in an industry standard easy-to-use E1B package. The modules utilize a unique cascode architecture that pairs a high performance normally-on SiC JFET with a cascode optimized low voltage, low RDS(on) Si MOSFET, producing a normally off device with reduced conduction and switching losses for maximized efficiency. The silicon-like gate drive characteristics allows for the use of standard unipolar gate drive levels compatible with Si IGBTs, Si FETs, SiC MOSFETs or…

What made you select MRC Components Nanocrystalline Filtercores as a product to feature?When I was a child growing up in Sigmaringen, Germany, I remember being in the kitchen with my mother baking cakes. There was a small radio that played music. The oven was a gas stove, there was no microwave or other electrical appliances in the kitchen. As soon as my mother started the mixer for the cake batter, I heard the hum on the radio…Today we have a variety of electrical appliances in the kitchen and, thanks to interference filters in each appliance, we no longer hear a…
The Ultimate RF Filter Guide: How to Maximize Signal Integrity, by Colin Field Navigating the complex realm of electronic design requires a thorough understanding of RF filter technology. Designed to eliminate unwanted interference, improve signal integrity, and prevent signal distortion, RF filters are a key consideration in the development of wireless communication systems. Spectrum usage is closely controlled by the ITU (International Telecommunications Union) and achieving the emissions limits of most communications protocols will require some form of filtering technology. As filter technology rapidly evolves and spectrum usage expands towards higher frequencies, system engineers are faced with an ever more…

What made you select the Qorvo UJ4SC075009B7S as product to feature? How does this product differentiate from others and what value does it offer?Qorvo’s UJ4SC075009B7S is an AEC-Q101 Qualified 750 V, 9 mΩ Gen 4 SiC FET. Its distinctive stacked cascode circuit configuration integrates a normally-on SiC JFET alongside a Si MOSFET, resulting in a normally-off SiC FET device. The stacked design also creates more space for larger die allowing for lower RDS(on) performance in the same package size, and the 750V rating offers enhanced voltage transient margin over similar 600 – 650V rated devices. The gate-drive characteristics allows for…
