RFFC2071SR
型號：
RFFC2071SR
品牌：
QORVO/RFMD
產品分類：
射頻混合器
描述：
詳細描述,The RFFC2071 is a re-configurable frequency conversion device with integrated fractional-N phased locked loop (PLL) synthesizer, voltage controlled oscillator (VCO) and?two high linearity mixers. 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 2700MHz. The LO signal is buffered and routed to the integrated RF mixers which are used to up/down-convert frequencies ranging from 30MHz to 2700MHz. The mixer bias current is programmable and can be reduced for applications requiring lower power consumption. , ,The device can be configured to work as signal sources by bypassing the integrated mixers. 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 (e.g. the LOCK signal) or to control front end components. The device operates with a 2.7V to 3.3V power supply. ,特點,85MHz to 2700MHz 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,Integrated Phase Noise 0.18° rms at 1GHz,High Linearity RF Mixers,30MHz to 2700MHz Mixer Frequency Range,Input IP3 +23dBm,Mixer Bias Adjustable for Low Power Operation,Full Duplex Mode,2.7V to 3.3V Power Supply,Low Current Consumption,3- or 4-Wire Serial Interface

RFSA4013TR7
型號：
RFSA4013TR7
品牌：
QORVO/RFMD
產品分類：
衰減器
描述：
詳細描述, ,RFMD's RFSA4013 is a fully monolithic analog temperature compensating attenuator (TCA) featuring exceptional linearity over its entire gain control range. It is designed to offset the gain reduction of an RF component over temperature without the need for closed loop feedback. Three customer selectable temperature coefficients make it a flexible solution for RF lineups. It incorporates revolutionary new circuit architecture to solve a long standing industry problem with regards to attenuator architecture: high IP3, low DC current and broad bandwidth. Traditional approaches for solving this problem require expensive co-fired ceramics with temperature sensitive materials or current hungry PIN diodes with elaborate area consuming control circuits. This temperature compensating attenuator requires only a single supply voltage and two logic bits to set control attenuation slope versus temperature. The RFSA4013 draws a very low 1mA current and is packaged in a small 3mm?x?3mm QFN. This attenuator is matched to 50? over its rated control range and frequency with no external matching components required.,特點,Patent Pending Circuit Architecture,Broadband 50MHz to 6000MHz Frequency Range,3 Selectable Attenuation versus Temperature Slopes,+55dBm IIP3 Typical,+85dBm IIP2 Typical,High 1dB Compression Point >+30dBm,Low Supply Current 1mA Typical,5V Power Supply,Class 1C ESD ( 1000V ),Complete Solution in a Small 3mm x 3mm QFN Package,3.3V Part Available - RFSA4023
