Ampleon introduces the industry's most robust 12V LDMOS power amplifier

     Ampleon announced its latest 12V transverse diffusion metal-oxide semiconductor (LDMOS) transistor product line, strengthening its terrestrial mobile radio business. The new 12V LDMOS platform is based on Efulon's proven 9th generation LDMOS technology for commercial, public safety and defense mobile radio applications. The new 12V LDMOS products include ceramic and plastic packages and are promised a minimum production life of 15 years.

     The two first products are the BLP9LA25S and BLP5LA55S. Both 12V devices are available across the entire VHF and UHF bands from 2MHz to 941MHz, offering 25W and 55W outputs, respectively. They combine the advantages of being simple to use and extremely reliable, and the performance is also excellent. A gain of > 18dB and an efficiency of > 65% are achieved over the entire operating frequency range, which reduces the number of amplification stages, improves stability, simplifies the cooling unit, and reduces the system volume.

     They also have excellent linearity, making them ideal for terrestrial trunking radio (TETRA) applications, and they can withstand extreme mismatches in excess of 65:1 voltage standing wave ratio (VSWR) to withstand the harshest application environments, making them ideal for hand-held radio stations where reliability requirements are high. In addition, both wideband 12V devices are available in a compact Supermolded plastic (OMP) TO270 package for small size and low cost.
