PBL 403 07 GSM Dual Band Tx_VCO Key Features • One IC handles GSM900 DCS 1800/ PCS 1900 bands • High output power: (17 dBm, 13dBm/ 13dBm) 07 L B P 3 40 16 pin QSOP Description The PBL 403 07 is a Dual Band Tx_VCO for use in GSM dual band terminals. The resonators for each band are external. The resonator consists of varactor, capacitor and inductor in series from ground to the VCO resonator pin. The inductor, capacitor and varactor determines the oscillation frequency, and also the tuning range.
