产品应用︰Ku 频段的DVB-S的接收
Designed for use in the Low Noise Block (LNB) of a Ku-bandsatellite receiver for Asian and European standards, the NXPTFF1004HN is a highly integrated IC that includes an LNA, a mixer,a down-converter, a PLL, a crystal oscillator, and an IFbuffer.It is manufactured in NXP’s breakthrough SiGe BiCMOS process formicrowave applications, which is more costeffective than GaAsprocesses and more reliable than discrete implementations.
To comply with Asian and European DVB-S standards, the TFF1004HNsupports RF input frequencies between 10.7 and 12.75 GHz, and usesa selectable LO that operates at 9.75 or 10.6 GHz.
It is housed in a small HVQFN24 package that measures only 4 x 4x 0.85 mm, and is designed to work as part of a complete chipsetthat provides a total LNB solution.Create a Ku-band DVB-S LNB for less, with higher reliability TheTFF1004HN is an integrated downconvertor for use in Low Noise Block(LNB) convertors in a 10.7 GHz to 12.75 GHz Ku band satellitereceiver system. This alignment-free concept replaces currentsolutions that require components such as GaAs mixer and DRO. Aspart of our LNB chipset, it enables a Ku-band satellite receiverthat lowers total cost of ownership and guarantees the stability ofthe local oscillator.
完整的LNB设计解决方案The chipset consists of the TFF1004HN, the UAF3000TS, and theBFU725F.The UAF3000TS is a FET bias controller with a polarization switchand tone detection. It provides biasing for up to three LNAdevices. An integrated bandgap reference ensures the accuracy ofvoltage and tone detection, also over temperature.For horizontal and vertical switching, there is an integratedsupply-voltage detector, and for switching between high and lowbands, there is a 22-kHz tone detector. The supply voltage range,3.3 V or 5 V, is detected automatically. The BFU725F is an NPNmicrowave transistor for high-speed, low-noise applications. In theLNB chipset, it is used for the second LNA stage. It ismanufactured in a 110-GHz fT-SiGeC technology,so it delivers an excellent noise figure (1.0 dB at 12 GHz), and ahigh maximum stable gain (13 dB at 12 GHz).
