Rugged 12V LDMOS power amplifiers join land mobile radio line-up
A new line of 12V laterally diffused metal oxide semiconductor (LDMOS) transistors bolsters Ampleon’s land mobile radio portfolio.
This 12V LDMOS platform is based on the 9th generation of Ampleon’s LDMOS technology and will target commercial, public safety and defence mobile radio applications, and the portfolio covers ceramic and plastic packages.
The first two products to be released are the BLP9LA25S and the BLP5LA55S. These devices are designed for 12V nominal mobile operation over the entire VHF and UHF frequency bands from 2 to 941 MHz and deliver 25 W and 55 W respectively.
They combine ease-of-use with ruggedness, enabling greater than18 dB gain and more than 65 per cent efficiency over the full operating frequency range. This results in fewer stages, improved stability, simplified cooling and thus smaller systems, says the company.
Their linearity suits them to tetra applications and their capability to handle extreme mismatch levels over 65:1 voltage standing wave ratio equated to handheld radios that can withstand harsh environments .
These broadband 12V devices are housed in compact over-molded plastic (TO270 packages for a small footprint.
Qualification samples of both the BLP5LA55S and the BLP9LA25S are available via Ampleon’s local sales channels with reference circuits available at different frequency bands.
Production for both variants is expected in the last quarter of the year.
Ampleon has more than 1,650 employees worldwide. Its portfolio offers products and solutions for a range of applications, such as mobile broadband infrastructure, radio and TV broadcasting, carbon dioxide lasers and plasma, MRI, particle accelerators, radar and air-traffic control, non-cellular communications, RF cooking and defrosting and RF heating and plasma lighting.
