RF2416
DUAL-BAND 2.7V LOW NOISE AMPLIFIER
Typical Applications
• GSM/DCS Dual-Band Handsets
• Cellular/PCS Dual-Band Handsets
• General Purpose Amplification
• Commercial and Consumer Systems
Product Description
The RF2416 is a dual-band low noise amplifier with
bypass switch designed for use as a front-end for
950MHz GSM and DCS1800/PCS1900 applications. It
may also be used for dual-band cellular/PCS application.
The 900MHz LNA is a single-stage amplifier with bypass
switch; the 1800/1900 LNA is a two-stage amplifier with
bypass switch. Both amplifiers have excellent noise figure
and high linearity in both high gain and bypass/low gain
mode. The device is packaged in a 3mmx3mm, 12 pin,
leadless chip carrier.

Application Notes
Bypass Mode Configurations
The RF2416 may be placed into either high gain or bypass mode via the HB SELECT and LB SELECT pins for high
band and low band operation, respectively. The high gain state is selected by asserting the select pin for the appropriate
band to a voltage level of less than 0.8V. For Bypass operation, there are two possible methods for placing the RF2416
into this low gain state. The table below shows the two possible Bypass states for each mode.

For both Bypass configurations, the select pin for the appropriate band must be placed at a level greater than or equal to
1.8V. The difference between the Bypass possibilities is determined by the specific application’s ability to change the
voltage of the bias pins independently of VCC. The advantage of the ability to assert the bias pins to 0V when in Bypass
mode is shown by the decreased current draw when in this Bypass configuration.
