Characteristics
1) All the active devices of PG-1810 are made of semiconductors to ensure excellent performance
and semi-permanent use.
2) Surface mounting device (SMD) is used to ensure high reliability, compactness and lightness.
3) PG-1810 adopts the Silabs’s AERO
Ⅱ
RF transceiver(Si4210), which is CMOS RF front-end for
multi-band GSM digital cellular handsets. The Aero's highly-integrated architecture eliminates
the IF SAW filter, low noise amplifiers (LNAs) for three bands, transmit and RF voltage-controlled
oscillator (VCO) modules, and more than 60 other discrete components found in conventional
GSM handsets to deliver smaller, more cost effective GSM solutions that are easier to design
and manufacture.
