Ampleon launches rugged 12V LDMOS power amplifiers for land mobile radio

Ampleon has launched a new line of 12V laterally diffused metal oxide semiconductor (LDMOS) transistors to support its land mobile radio portfolio.

The 2V LDMOS platform is based upon the proven 9th generation of Ampleon’s LDMOS technology and will target commercial, public safety and defence mobile radio applications.

The 12V LDMOS portfolio will cover ceramic and plastic packages with a minimum longevity commitment of 15 years.

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 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 linearity makes them suitable 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.

In addition, these broadband 12V devices are housed in compact over-moulded plastic (OMP) TO270 packages, ensuring smallest footprint and minimising system costs.
