射頻混合器

詳細(xì)描述,The RF2053 is a low power high performance wideband RF frequency conversion chip with integrated local oscillator (LO) generation and RF mixer. The RF synthesizer includes an integrated fractional-N phase locked loop that can control an external VCO to produce a low-phase noise LO signal with a very fine frequency resolution., ,The VCO output frequency can be divided by 1 2 or 4 in the LO divider whose output is buffered and drives the built-in RF mixer which converts the signal into the required frequency band. The mixer bias current can be programmed dependent on the required performance and available supply current. The LO generation blocks have been designed to operate with external VCOs covering the frequency range from 300MHz to 2400MHz. The RF mixer is very broad band and operates from 30MHz to 2500MHz at the input and output enabling both up and down conversion. An external crystal of between 10MHz and 52MHz or an external reference source of between 10MHz and 104MHz can be used with the RF2053 to accommodate a variety of reference frequency options. All on-chip registers are controlled through a simple three-wire serial interface. The RF2053 is designed for 2.7V to 3.6V operation for compatibility with portable battery powered devices. It is available in a plastic 32-pin 5mmx5mm QFN package. ,特點(diǎn),Fractional-N Synthesizer,Very Fine Frequency Resolution 1.5Hz for 26MHz Reference,300MHz to 2400MHz External VCO Frequency Range,On-Chip Crystal-Sustaining Circuit With Programmable Loading Capacitors,Integrated LO Buffer and LO Divider,High-Linearity RF Mixer,Mixer Input IP3 +23dBm Typ.,Mixer Bias Adjustable for Low Power Operation,Mixer Frequency Range 30MHz to 2500MHz,2.7V to 3.6V Power Supply,Low Current Consumption 50mA to 70mA at 3V,3-Wire Serial Interface

射頻混合器

詳細(xì)描述, ,The RFFC5072 is a reconfigurable frequency conversion device with integrated fractional-N phased locked loop (PLL) synthesizer, voltage controlled oscillator (VCO) and a high linearity mixer. The fractional-N synthesizer takes advantage of an advanced sigma-delta modulator that delivers ultra-fine step sizes and low spurious products. The PLL/VCO engine combined with an external loop filter allows the user to generate local oscillator (LO) signals from 85MHz to 4200MHz. The LO signal is buffered and routed to the integrated RF mixer which is used to convert frequencies ranging from 30MHz to 6000MHz. The mixer bias current is programmable and can be reduced for applications requiring lower power consumption. , ,RFFC5072?can be configured to work as a signal source by bypassing the integrated mixer. Device programming is achieved via a simple 3-wire serial interface. In addition, a unique programming mode allows up to four devices to be controlled from a common serial bus. This eliminates the need for separate chip-select control lines between each device and the host controller. Up to six general purpose outputs are provided, which can be used to access internal signals (LOCK signal, for example) or to control front end components. The RFFC5072 operates with a 2.7V to 3.3V power supply. ,特點(diǎn),85MHz to 4200MHz LO Frequency Range,Fractional-N Synthesizer with Very Low Spurious Levels,Typical Step Size 1.5Hz,Fully Integrated Low Phase Noise VCO and LO Buffers,High Linearity RF Mixer(s),30MHz to 6000MHz Mixer Frequency Range,Input IP3 +23dBm,Mixer Bias Adjustable for Low Power Operation,2.7V to 3.3V Power Supply,Low Current Consumption,3- or 4-Wire Serial Interface
