PRODUCT DESCRIPTION
CHP1237 is an InGaP HBT amplifier module
offering high performance for PCS CDMA wireless
handsets. It consists of a two-stage amplifier, 50 Ω
matching network for both input and output, and a
bias control circuit. It is packaged in a 3 x 3 x 1 mm
package using proprietary Passive-Free Technology
(PFT)TM. The package provides excellent electrical
stability and low thermal resistance.
