Description 
The Geo-Chip GC0658 is a band 5/8 power amplifier module (PAM), mainly designed for internet-of-things applications at low voltage supply, such as NB-IOT. The GC0658 is typically working at 2.4V power supply, and could function properly even at 1.8V power supply which satisfied most low voltage applications. The GC0658 is specifically optimized its performance in 824-849MHz Band 5 and 880-915MHz Band 8 frequency range.
Packaged in a compact LGA 2.5 mm x 2.0 mm x 0.75mm, the GC0658 is a 10-pad surface mount PAM, exhibits high efficiency, low temperature variation, strong reliability and robust ruggedness.
