F1129LB
Datasheet
Description
The F1129LB is a single-ended input / differential output 1.4GHz to
3.2GHz high gain RF amplifier. The combination of impedance
translation, high gain, high linearity, and low noise performance
makes this device an ideal amplifier for a variety of receiver
applications.
The F1129LB has been optimized to operate with a single 5V
power supply and a nominal 61mA of ICC. When operated at
2.5GHz, the device provides 20dB typical gain with 1.6dB noise
figure and +36dBm OIP3.
The F1129LB is pin-compatible with Renesas’ F1129xx family of
RF amplifiers, offering additional frequency and output impedance
options. Each F1129 variant is packaged in a 2 × 2 mm, 12-DFN,
with a 50Ω single-ended RF input and 50Ω or 100Ω differential RF
output impedances for ease of integration in the signal path.
