Abstract

This paper describes the antenna and input stages of a silicon TV-tuner intended for portable devices such as cell phones, laptops and PDAs. The tuner meets the requirements of the mobile and portable DVB-T radio access interface specifications MBRAI. The first stages of the tuner comprise a broadband antenna, a matching and filtering circuit, and LNA. The frequency band of operation is 470-710MHz (DVB-H). The matching and filtering circuitry comprises a strong GSM trap that attenuates the GSM frequencies by more than 40dB. The overall power gain is 20 ± 3dB in the band, and the NF of the total chain is less than 4dB. The power consumption is 21mW from 2.5V supply. The LNA is fabricated in a 0.25μm, 35GHz f_T BiCMOS technology based on D. Szmyd et al. (2001).
