What made you select Marki’s MFBC-0000XPSM family as products to feature? I’ve chosen the MFBA-0000XPSM series of MMIC surface mount bandpass filters due to the repeatability, higher frequency operation and small form factor.  It’s not common to find this type of performance and consistency at this size and cost! What are the key features and specifications of the MFBC-0000XPSM family? With center frequencies ranging from 7.90 GHz to 36 GHz, this family of filters features excellent stopband suppression and fast roll-off.  They have also undergone extensive testing to show minimal variability over temperature and can even handle up to 10W.…

Traditional base-station RF power amplifiers often use Laterally-diffused Metal-oxide Semiconductor (LDMOS) devices to meet cost-efficiency requirements. To boost performance, many designers are now exploring alternative design solutions using high-performance GaN devices or GaN on SiC Power Amplifiers. However,  several challenges make GaN devices significantly different from your standard LDMOS FET devices.  Five considerations for designing with GaN devices include Bias Sequencing, Vgs Drift, Temperature Compensations Requirements, Gate Leakage current requirements and the Thermal Measurement Process for MTTF Calculations. Figure 1: Typical GaN HEMT structure.

Although GaN transistors have been popular in recent years for broadband and high-frequency applications, LDMOS is still the leading technology for high-power amplifier designs from HF to UHF. The sweet spot for rugged LDMOS is below 450MHz, and with the correct thermal design, rugged devices will withstand very high levels of VSWR up to 65:1. Initially designed for broadcast and industrial applications in the mid-nineties, we have seen power levels and breakdown voltages improve with successive generations. Design Limitations As generations of LDMOS advance (Ampleon is now working on Generation 12), I am often asked about even higher-power rugged transistors.…
