General Description
The TQP3M9035 is a high linearity low noise gain block amplifier in a low-cost surface-mount package.
At 1.
9 GHz, the amplifier typically provides 16.
5 dB gain, +37.
0 dBm OIP3, and 0.
66 dB Noise Figure.
The LNA is also designed to be broadband without the requirement for external matching.
The device is housed in a leadfree/green/RoHS-compliant industry-standard 2x2mm package.
The TQP3M9035 has the benefit of having high linearity while also providing very low noise across a broad range of frequencies.
This allows the device to be used in both receive and transmit chains for high performance systems.
The amplifier is internally matched using a high performance E-pHEMT process and only requires an external RF choke and blocking/bypass capacitors for operation from a single +5V supply.
The low noise amplifier integrates a shut-down biasing capability to allow for operation for TDD applications.
The TQP3M9035 covers the 0.
05 - 4 GHz frequency band and is targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
