Rugged 12V LDMOS power amplifiers for land mobile radio | Ampleon
This new 12V LDMOS platform is based upon the proven 9th generation of Ampleon’s LDMOS technology and will target commercial, public safety and defense mobile radio applications

Ampleon launches its new line of 12V laterally diffused metal oxide semiconductor (LDMOS) transistors and bolsters up its land mobile radio portfolio. The new 12V LDMOS portfolio will cover ceramic and plastic packages with a minimum longevity commitment of 15 years.

The first 2 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 and extreme ruggedness without sacrificing performance, as they enable >18 dB gain and >65% efficiency over the full operating frequency range. This results in fewer stages, improved stability, simplified cooling and thus smaller systems. Their excellent linearity makes them ideal for tetra applications and their capability to handle extreme mismatch levels over 65:1 voltage standing wave ratio (VSWR) enables highly robust handheld radios that withstand harshest environments possible. Furthermore, these broadband 12V devices are housed in compact over-molded plastic (OMP) TO270 packages, ensuring smallest footprint and minimizing system costs. 

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 2019.
