Preliminary
Product Description
The SPB-3018 is high-efficiency InGaP/GaAs Heterojuction Bipolar
Transistor (HBT) amplifier RFIC. This amplifier incorporates an on-chip
Class AB bias circuit which provides excellent efficiency while maintain-
ing good linearity. The on-chip bias also allows the device output power
(and current) to drive up towards saturation as the input power in-
creases. The SPB-3018 is an ideal choice for multi-carrier as well as
digital wireless telecom or general wireless applications in the 400-2500
MHz range. This amplifier is a robust, reliable, and rugged part with
Class 1C HBM ESD rating, low operating junction temperature (Tj<125 ºC
at 85 ºC lead), and excellent moisture resistance (MSL 1).
