At IMS 2025, Tim Daly from RFMW speaks with Baljit Chandhoke, Product Manager at Microchip, about two innovative RF products.
First up is the MMA051PP45, a DC to 22 GHz GaAs MMIC distributed power amplifier that delivers 1W output power in a compact 4.5 x 4.5 mm QFN package. With 15 dB of gain and a 10V supply, this device is ideal as a broadband gain block. Microchip also offers variants such as the MMA052 and MMA053, the latter featuring a 2.8 dB noise figure and positive gain slope—giving engineers flexible options for designing complete RF signal chains.
The second highlight is the newly released 101765 ultra-low phase noise VCSO, which features an impressive -180 dBc/Hz noise floor and -160 dBc/Hz at 10 kHz offset. This oscillator is ideal for use as a local oscillator or clock source in radar, mil/aero communications, test and measurement, and satellite systems.
Baljit also emphasizes Microchip’s unique position in offering a complete RF signal chain solution, from GaN-on-SiC power amplifiers and low-noise amplifiers to PLL building blocks and oscillators—supporting applications in aerospace and defense, SATCOM, 5G, and more.
Both products are in production and available now through RFMW.
