RFMD ramps PAs for “ET revolution”

RFMD has commenced high-volume manufacturing of energy amplifiers (PAs) and energy management integrated circuits (ICs) incorporating envelope tracking (ET) engineering.

This follows yesterday’s announcement type Texas Instruments that it was introducing its first envelope monitoring electrical power provide for LTE mobile phones.

ET-enabled PAs are constantly adjusted so that the amplifier operates at greatest power efficiency. The outcome is decrease battery power consumption. That is notably eye-catching in 4G LTE mobile platforms, which operate in numerous frequency bands and call for quite a few separate PAs.

RFMD stated its PA delivers full ET compatible coverage of all FD-LTE and TD-LTE bands (1-14, 17-21, 25-28, 38, 40, 41, and 44).

Its envelope tracking-enabled PAs involve RF7389 and RF8085 multimode, multi-band PAs, the RF80xx(i) family members of 10 single-band satellite PAs, and its RF8081 ET power management IC.

“This volume ramp-up of a broad loved ones of envelope tracking-enabled products puts RFMD in the forefront of the ET revolution,” said Eric Creviston, president of RFMD’s Cellular Products Group.

Texas Instruments has announced its 1st envelope monitoring electrical power provide chip, which it claims will reduce power consumption in 3G and 4G LTE multi-mode, multi-band RF electrical power amplifiers (PAs) utilized in smartphones and tablets.

This can see it competing during the 4G smartphone industry against UK-based envelop-tracking silicon supplier, Nujira.
