Sharp is expanding its product portfolio of its Network Interfaced Module (NIM) tuners for the digital reception of High-Definition TV through satellite with a particularly power-saving model. The new DVB-S2 NIM tuner type BS2F7HZ0167 is content with a power input of, typically, around 1.5 watt. The new addition to the DVB-S2 tuner family has an identical casing to the existing DVB-S2 NIM tuner and is, for this reason, completely hardware-compatible in mechanical terms. In addition, the BS2F7HZ0167 completely encompasses the typical satellite reception frequency field of between 950 and 2150 MHz and is suitable for the reception of HDTV signals in the DVB-S2 standard as well as for standard DVB-S signals. The BS2F7HZ0167 features good technical parameters. The noise figure (NF) here is around 6dB (typically) and the phase noise is around -80dBc/Hz (typically) at 10kHz offset. When it comes to signal input sensitivity, dynamics and definition the new DVB-S2 NIM Tuner offers high performance.

The NIM demodulator unit of the BS2F7HZ0167 is fitted with the recent chip from ST Microelectronics - the STV0903 model. This provides an 8PSK / QPSK demodulation and delivers a digital 8-bit data-stream for further signal processing. With the models BS2S7VZ0604 and BS2S7HZ0604, the Japanese corporation also supplies the new DVB-S2 tuner as pure RF frontends for upright or flat-lying mounting. They too have the same degree of high-quality reception characteristics as the newly introduced DVB-S2 tuners. The new DVB-S2 NIM tuner of the BS2F7HZ0167 model is available from May 2008 through Sharp sales offices and distribution partners.
