PXAD184218FV
Thermally-Enhanced High Power RF LDMOS FET
420 W, 28 V, 1805 – 1880 MHz
Description
The PXAD184218FV is a 420-watt (P
) LDMOS FET with an
3dB
asymmetrical design intended for use in multi-standard cellular
power amplifier applications in the 1805 to 1880 MHz frequency
band. Features include dual-path design, input and output matching,
high gain and thermally-enhanced package with earless flanges.
Manufactured with Infineon's advanded LDMOS process, this device
provides excellent thermal performance and superior reliability.
