programmable gain rf amplifier


Low noise RF amplifier with programmable gain Download PDF Info Publication number US6181206B1. Filter by maximum voltage gain, pin count and more. Maxim MAX3522B is a Programmable Gain Amplifier (PGA) designed to exceed the Data Over Cable Service Interface Specification (DOCSIS) 3.1 Upstream Transmit requirements. MAX3522B has dual outputs, which eliminates the need for an external RF switch when selecting between two different upstream bandwidths. Some RF amplifiers offer a single fixed-gain value, while others allow the user to select among fixed-gain values (such as ×10 and ×100, or ×2, ×4, ×8, ×16) via an external jumper or resistor. New Programmable Gain Instrumentation Amp The ADA4254 is a zero drift, high voltage, low power programmable gain instrumentation amplifier (PGIA), designed for … The PGA103 is a programmable-gain amplifier for general purpose applications. The PGA meets the DOCSIS 3.1 spurious limits while transmitting a combined output power of 68dBmV over the RF bandwidth of 5MHz to 204MHz. Programmable Gain Amplifiers: 129 Products Found Filter Layout: LEFT. The newest report on ' Programmable & Variable Gain Amplifiers market' now available a MarketStudyReport.com, offers concise facts about the geographical landscape, industry size and revenue estimation of the business. ADI's AD8271 low-distortion, programmable-gain difference amplifier comprises a precision op-amp and seven laser-trimmed gain-setting resistors, enabling user-selectable differential gains of 0.5, 1, or 2. TOP. The DS4420 is a fully differential, programmable gain amplifier for audio applications. The PGA103 is ideal for systems that must handle wide dynamic range signals. R(DAC) = R/2×[4096/(DAC CODE)], with the DAC CODE given as a decimal value. The gain can be set from less than 1 to over 100 volts. Order in single or bulk quantities. This report presents the worldwide Programmable & Variable Gain Amplifiers market size (value, production and consumption), splits the breakdown (data status 2018 and forecast to 2025), by manufacturers, region, type and application. Programmable Gain Amplifiers (PGA) Programmable Gain Amplifiers are Operational, Instrumentation or Differential Amplifiers in which the gain can be programmed or selected, either via hardware (IC pin selection) or software using a serial communications link. *Required. Abstract: By selecting a particular configuration of an input stage of a low noise RF amplifier, an optimal combination of linearity and input matching is achieved upon selecting a certain gain factor from a set of fixed step values. Certain designs need a programmable-gain amplifier with a wide gain range and high accuracy and common-mode rejection. A programmable-gain amplifier (PGA) is an electronic amplifier (typically based on an operational amplifier) whose gain can be controlled by external digital or analog signals. *A Page 5 of 16 void PGA_Start(void) Description: This is the preferred method to begin component operation. The DAC functions as a programmable resistor in the feedback of the amplifier such that : V OUT /V IN = -R(DAC)/RFB, where R(DAC) is the resistance of the DAC ladder and RFB is the value of the feedback resistor, which is R/2. Per channel there is one transimpedance amplifier between a current input INX and a voltage output OUTX. It features a -35dB to +25dB gain range controlled by an I²C interface and it is optimized to drive loads as low as 50Ω. Variable gain amplifiers deliver unmatched performance for signal chains that require high dynamic range. It can also be configured in over 40 single-ended configurations, with gains ranging from -2 to +3. But all these features come with a cost, and for me, it's not worth putting that costly of a chip for a generic application. Choose from selectable gain amplifiers, programmable gain op amps, and other types of programmable gain amplifiers available at affordable prices! The programmable gain amplifier consists of the analog switch in the feedback network which consists of the resistors of different values and comprises the selection pins through which one of the resistors can be selected to achieve the required gain. The PGA103’s high speed circuitry provides fast set-tling time, even at G=100 (8µs to 0.01%). PSoC fi CreatorŽ Component Datasheet Programmable Gain Amplifier (PGA) Document Number: 001-70324 Rev.
