What is the Surface Mount ?

having leads that are designed to be soldered on the side of a circuit board that the body of the component is mounted on.

What is the Operating Temperature ?

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

What is the Packaging ?

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

What is the Part Status ?

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

What is the Terminal Form ?

Occurring at or forming the end of a series, succession, or the like; closing; concluding.

What is the Terminal Pitch ?

The center distance from one pole to the next.

What is the Max Supply Voltage ?

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

What is the Min Supply Voltage ?

The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.

What is the Nominal Supply Current ?

Nominal current is the same as the rated current. It is the current drawn by the motor while delivering rated mechanical output at its shaft.

What is the Quiescent Current ?

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero.

What is the Synchronous Rectifier ?

Synchronous rectification is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT).

What is the RoHS Status ?

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

The ADRF6821ACPZ is a highly integrated, dual radio frequency (RF) input, zero intermediate frequency (IF)/low IF RFIC receiverwith a quadrature demodulator, digital step attenuator (DSA),IF linear amplifiers, an integrated, fractional-N phase-locked loop (PLL), and a low phase noise, multicore, voltage controlled oscillator (VCO). The RFIC is ideally suited for communication digital predistortion (DPD) systems.

The high isolation 2:1 RF switch and on-chip wideband RFbalun enable the ADRF6821ACPZ to support two single-ended, 50 Ω terminated RF inputs. A programmable attenuator ensures anoptimal differential RF input level to the high linearity demodulatorcore. The integrated attenuator offers an attenuation range of 15 dB with a step size of 1 dB. High linearity IF amplifiers follow the demodulator and provide an interface to the next componentin the chain, typically an analog-to-digital converter (ADC).

The ADRF6821ACPZ offers two alternatives for generating thedifferential local oscillator (LO) input signal: internally viathe on-chip fractional-N synthesizer with low phase noiseVCOs or externally via a low phase noise LO signal. Theintegrated synthesizer enables continuous LO coverage from 450 MHz to 2800 MHz. The PLL reference input supports awide frequency range and includes integrated reference dividers before the phase frequency detector (PFD).

When selected, the output of the internal fractional-N synthesizeris applied to a divide by 2, quadrature phase splitter. From theexternal LO path, a 2× LO signal can be used with the divide by 2,quadrature phase splitter to generate the quadrature LO inputs to the mixers.

The ADRF6821ACPZ is fabricated using an advanced silicon germanium(SiGe), bipolar complementary metal oxide semiconductor(BiCMOS) process. It is available in a 56-lead, RoHS compliant,8 mm × 8 mm LFCSP package with an exposed pad. Performanceis specified over the −40°C to +105°C case temperature range.
