Abstract :
A multi-standard multi-band tuner for mobile TV SoC satisfying the GSM850 & GSM900 Interoperability (IOP) is presented. The single-chip SoC satisfies all requirements of DVB-H/T, ISDB-T, and DAB application with margin. Moreover, this SoC meets not only the GSM900 IOP which is described in MBRAI 2.0, but also GSM850 IOP, in DVB-T/H mode. To suppress GSM transmitter signal in UHF band, LC-tuned load and tunable input matching scheme are adopted in UHF LNA. The SoC consists of three RF LNAs covering the 174 to 248MHz (VHF), 470 to 862MHz (UHF), and 1450 to 1490MHz (L-BAND) bands, dual mode analog baseband filter supporting low pass filtering for direct conversion in DVB-H/T mode and complex band pass filtering for low-IF conversion in ISDB-T 1-segmentation and DAB. The measured sensitivity at UHF for the QPSK 1/2 DVB-T mode is under -95.5dBm with GSM rejection filter.
