RF VGA targets wireless infrastructure
Analog Devices is introducing the industry's first single-chip RF variable-gain amplifier/attenuator that operates at RF power levels for wireless infrastructure equipment.
Analog Devices is introducing the industry's first single-chip RF VGA (variable-gain amplifier/attenuator) that operates at RF power levels for wireless infrastructure equipment The ADL5330 is also the first monolithic VGA to provide broadband operation from 1MHz to 3GHz with a precision 60dB linear-in-decibels gain-control range

A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
These features, critical to demanding radio designs, have never before been available within a single IC.
Unlike conventional discrete solutions that require many external components, the single-chip ADL5330 integrates broadband amplifiers and attenuators, offering considerable savings in board area, component count and solution cost as compared with discrete implementations.
The precision linear-in-decibels control interface further simplifies and eases circuit design.
The ADL5330 provides 60dB dynamic gain and attenuation (approximately +20dB gain and -40dB attenuation), an output power level of 22dBm (1dB compression point), an output third-order intercept (OIP3) of +31dBm at 1GHz and a noise figure (NF) of 8dB.
The wide dynamic range of the ADL5330, combined with its low distortion and low noise, makes the device an ideal choice for transmit signal paths - at both RF and IF frequencies - within wireless infrastructure equipment such as cellular basestations (CDMA, W-CDMA, GSM), point-to-point and point-to-multipoint radio links, satellite equipment, wireless local loop and broadband access services.
The ADL5330 is an ideal companion to Analog Devices' I/Q modulators (AD8345, AD8346 and AD8349) and power detectors (AD8313, AD8314 and AD8362).
Using the ADL5330 in conjunction with these devices can enable a complete transmit signal path.
The ADL5330 single-chip VGA is currently sampling in 24-lead (4 x 4mm) chip-scale packaging (CSP) and is priced at $4.98 per unit in 1000-piece quantities.
Full production will begin in February 2005.
