High linearity power amplifiers boost cellular base station effectiveness
The 8860 power amplifier covers the frequency range 1.3 to 1.5 GHz, while the 8862 power amplifier covers the frequency range 2.3 to 2.7GHz. Both deliver a minimum linear output power (P1) of 19 W, with high gain, ±1 db gain flatness and excellent phase linearity across the whole frequency range.
Today’s base station amplifiers must be able to cope with multicarrier signals, high data rates and a wide range of wireless standards. With their high linearity, the 8860 and 8862 power amplifiers provide excellent error vector magnitude (EVM) with even the most complex waveforms to meet the demands of the latest generations of digital systems, ensuring reliable cellular coverage even under rapidly changing conditions.
The 8860 is built on GaN technology while the 8862 is designed using laterally diffused metal-oxide semiconductor (LDMOS) technology in a Doherty configuration. Both deliver high efficiency power in a compact form factor. Measuring 180 x 75 x 20 mm and weighing 400 g, the 8860 and 8862 power amplifiers provide an SMA RF connector and a 9-way D-type connector for control and monitoring.
Suitable for use in ambient temperatures from -40 °C to +55 °C and relative humidity up to 95 percent, the 8860 and 8862 power amplifiers are vibration resistant to IEC 68-2-6 and shock resistant to IEC 68-2-27, ensuring reliable long term operation in demanding environmental conditions.
