50Ω SE-In – 100Ω DIFF-Out Amplifier 1.4GHz to 3.2GHz 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.
