Description

The F1429MB is a differential input / single-ended output 3.0GHz

to 4.2GHz high-gain RF amplifier. The combination of impedance

translation, high gain, high linearity, and low noise performance

makes this device an ideal first-stage amplifier for a variety of

transmitter applications.

The F1429MB is optimized to operate with a single 5V power

supply and a nominal 73mA of ICC. When operated at 3.55GHz, the

device provides 21dB typical gain with 1.8dB noise figure, +40dBm

OIP3, and +21dBm OP1dB.

The F1429MB is pin-compatible with Renesas’ F1429xx family of

RF amplifiers (shown below). Each F1429 variant is packaged in a

2 × 2 mm, 12-pin DFN, with a 100Ω differential RF input and 50Ω

single-ended RF output impedances for ease of integration into the

signal path.
