Microchip Enhances BJT Reliability for Demanding Environments:
- Enhanced Low-Dose Radiation Sensitivity (ELDRS) Qualification: Microchip's JAN-qualified transistors are now rigorously tested and qualified according to the stringent requirements of MIL-STD-750, Test Method 1019, and MIL-PRF specifications.
- ELDRS Significance: This critical qualification ensures the resilience of small-signal bipolar junction transistors (BJTs) against performance degradation from prolonged exposure to low-dose radiation. In space and military applications, even minor variations in BJT parameters like current gain (beta), base current, and leakage currents can significantly impact circuit performance.
- Microchip's Solution: By undergoing ELDRS qualification and testing for radiation levels up to 100 Krad at 10 mrad per second, Microchip's JAN transistors guarantee reliable operation in low-dose radiation environments. They can also function consistently within a total ionizing dose (TID) range of 100 Krad to 1 Mrad.
Infineon's Radiation-Hardened FRAMs Offer Unmatched Data Retention:
- Long-Lasting Data Storage: Infineon's new radiation-hardened 1- and 2-Mb parallel interface ferroelectric RAMs (F-RAMs) boast an exceptional data retention capability of up to 120 years at 85°C.
- Benefits of F-RAMs: These non-volatile memory devices are highly valued in defense and space applications due to their ability to retain data and perform high-speed read/write operations even in harsh radiation environments. Radiation hardening further enhances their robustness, ensuring extended lifespans in satellites, space missions, and defense systems.
- Superior Reliability: Infineon's F-RAMs utilize a unique data storage mechanism that involves instantaneous switching of atomic states. This method offers superior stability and reliability compared to conventional trapped charge techniques, which are susceptible to data corruption from radiation or magnetic fields.

Qorvo Revolutionizes Radar Applications with Compact RF Modules:
- Reduced Board Space and Improved Signal Integrity: Qorvo's innovative integrated radio frequency (RF) multi-chip modules (MCMs) integrate multiple RF components (amplifiers, mixers, filters, antennas) into compact packages. This significantly reduces required board space and minimizes the need for complex routing on the PCB, ultimately enhancing signal integrity by minimizing parasitic inductance and capacitance.
- New MCM Offerings: Qorvo's latest additions include the QPF5001 (12-W, X-band front-end module), QPM2101 (S-band receive variable gain amplifier module), and QPB1029 (L-band filter bank module). These modules offer significant size reductions compared to discrete components and provide valuable functionalities for advanced radar applications.
