GENERAL DESCRIPTION
► Low-supply current
The ADRF5534 is an integrated RF, front-end multichip module
designed for time division duplex (TDD) applications. The device
operates from 3.1 GHz to 4.2 GHz. The ADRF5534 is configured
with an LNA and a high-power, silicon, SPDT switch.
► Receive operation: 120 mA typical at 5 V
► Transmit operation: 15 mA typical at 5 V
► Positive logic control
► 5 mm × 3 mm, 24-lead LFCSP package
In the receive operation at 3.6 GHz, the LNA offers a low noise
figure (NF) of 1.3 dB and a high gain of 35.5 dB with a third order
input intercept point (IIP3) of −4 dBm.
APPLICATIONS
► Wireless infrastructure
► TDD massive multiple input and multiple output (MIMO) and
active antenna systems
In the transmit operation, the switch provides a low insertion loss
of 0.8 dB and handles a long-term evolution (LTE) average power
of 37 dBm for a full lifetime operation (8 dB peak to average ratio
(PAR)) and 39 dBm for a single event (<10 sec) LNA protection
operation.
► TDD-based communication systems
The device is featured in an RoHS compliant, compact, 5 mm × 3
mm, 24-lead LFCSP package.
