Voltage Controlled Attenuator

Product Overview
Qorvo's RFSA2023 is a fully monolithic analog voltage
control attenuator (VCA) featuring exceptional linearity
over 30dB adjustment range with on-chip temperature
compensation.
RFSA2023 incorporates a revolutionary new circuit
architecture. It solved the long-standing industry
problems of IP3, attenuation range, DC current,
bandwidth, and temperature compensation. RFSA2023
is also designed with linear in dB control characteristic.
There is no external analog supporting circuitry
required. This attenuator is controlled by a single
positive variable voltage with DC conditioning circuitry
also on-chip. The slope of the attenuation versus control
voltage is selectable. The RFSA2023 draws only 1mA
current. It is internally matched to 50 Ω and works quite
well over its rated ranges of control voltage and
frequency.

Key Features
• Broadband 50MHz toꢁ6000ꢁMHz
• 30 dB Attenuation Range
• +50ꢁdBm Input IP3
• +80 dBm Input IP2
• >+30 dBm High 1 dB Compression
• 1mA Low Current Consumption
• 3.3V Power Supply
This game-changing product integrates the complete
solution into a small 3mm x 3mm QFN package. That
reduces the footprint by 20X in area and reduces the
DC power by 10X over the PIN diode approaches.
• Linear in dB Control Characteristic
• Internal Temperature Compensation
• 5V Version Available - RFSA2013

PCB Mounting Pattern
Notes:
1. All dimensions are in millimeters. Angles are in degrees.
2. Use 1 oz. copper minimum for top and bottom layer metal.
3. Via holes are required under the backside paddle of this device for proper RF/DC grounding and thermal dissipation. We recommend a 0.35mm
(#80/.0135") diameter bit for drilling via holes and a final plated thru diameter of 0.25 mm (0.01”).
4. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
