LMH9226
- Single-channel, single-ended input to differential output RF gain block amplifier
- Supports 2.6-GHz center frequency with
400-MHz, 1-dB bandwidth - 17-dB typical gain across the 1-dB bandwidth into ZLOAD = 50 Ω
- Noise figure < 3 dB in 1-dB bandwidth
- 35-dBm OIP3 at 2-dBm two-tone output power into ZLOAD = 50 Ω
- 17.5-dBm output P1dB into ZLOAD = 50 Ω
- 275-mW power consumption on 3.3-V single supply
- Up to TA = 105°C operating temperature
The LMH9226 is high-performance, single-channel, single-ended, 50-Ω input to differential 50-Ω or 100-Ω output RF gain block amplifier supporting a 2.3-GHz to 2.9-GHz frequency band. The device is well suited to meet requirements for 5G m-MIMO or small cell base station applications. The device integrates the functionality of a single-ended input and output RF gain block followed by a passive balun, where the device is mainly used in the final stage of a receiver signal chain to drive the full-scale voltage of an analog-to-differential converter (ADC) differential input.
The LMH9226 provides 17-dB typical gain with excellent linearity performance of 35-dBm output IP3 at 2.6 GHz, and maintains less than a 3-dB noise figure across the entire 1-dB bandwidth of 400 MHz. The device is internally matched for a 50-Ω impedance at the single-ended input. The differential output can easily interface to a 50-Ω impedance without any external matching circuitry. For 100-Ω impedance matching, an external matching circuitry is required that typically results in a 0.3-dB gain loss at 2.6 GHz.
Operating on a single 3.3-V supply, the device consumes approximately 275 mW of stand-by power, making the device suitable for high-density, 5G, massive multiple-input and multiple-output (MIMO) applications. Also, the device is available in a space-saving, 2-mm × 2-mm, 12-pin WQFN package. The device is rated for an operating temperature of up to 105°C to provide a robust system design. A 1.8-V JEDEC compliant power-down pin is available for fast power-down and power-up of the device that is suitable for time division duplex (TDD) systems.
