SX1701A – Datasheet
Highly linear wideband LNA
Single-channel, single-ended to differential conversion
GENERAL DESCRIPTION
The SX1701A is an integrated LNA operating over a
wide frequency range from 40 MHz to 2.5 GHz. It is
optimized for high OIP2 and OIP3 with minimum current
consumption. It also performs a single-ended to
differential conversion with 3 selectable gains.
APPLICATIONS
• Digital Set Top Boxes (Satellite and Terrestrial)
• CATV Distribution Systems
• Active Splitter
• Data Communications Systems
• Active Balun
KEY PRODUCT FEATURES
• Single-ended input / Differential outputs
• Programmable gain: 6, 12 and 18 dB
• High Linearity: OIP2 of 57 dBm and OIP3 of 22 dBm
• Noise Figure of 7 dB
• 75 Ω Input impedance
• 100 Ω differential output impedance
• Current consumption of 130 mA at maximum gain
• ESD protection (Normal ESD handling procedures
should be observed)
• Very small package: MLPQ-16, 4 mm x 4 mm
(equivalent to QFN-16, 4 mm x 4 mm)
