HMC902 Data Sheet THEORY OF OPERATION
The HMC902 is GaAs, pHEMT, MMIC, low noise amplifier. The HMC902 has single-ended input and output ports with The HMC902 amplifier uses two gain stages in series. The basic impedances nominal y equaling 50 Ω over the 5 GHz to 11 GHz schematic for the amplifier is shown in Figure 19, which forms a frequency range. Consequently, the device can be directly inserted low noise amplifier operating from 5 GHz to 11 GHz with excellent into a 50 Ω system with no required impedance matching circuitry, noise figure performance. meaning multiple HMC902 amplifiers can be cascaded back to
V
back without the need for external matching circuitry.
DD1 VDD2
The input and output impedances are sufficiently stable vs. variations in temperature and supply voltage so no impedance matching compensation is required.
RFIN RFOUT
It is critical to supply very low inductance ground connections to the exposed pad to ensure stable operation. To achieve optimal performance from the HMC902 and to prevent damage to the device, do not exceed the absolute maximum ratings. 019
