HMC320MS8G / 320MS8GE v03.0308 GaAs MMIC LOW NOISE AMPLIFIER , 5 - 6 GHz 8 Typical Applications Features The HMC320MS8G(E) is ideal for: Selectable Functionality: LNA, Driver, or LO Buffer Amp UNII Adjustable Input IP3 Up to +10 dBm HiperLAN +3V Operation Ultra Small 8 Lead MSOP: 14.8 x 14.8 x 1 mm Functional Diagram General Description The HMC320MS8G & HMC320MS8GE are low cost C-band fi xed gain Low Noise Ampl ifiers (LNA). The HMC320MS8G & HMC320MS8GE operate using a single positive supply that can be set between +3V and +5V. With +3V bias, the LNA provides a noise figure of 2.5 dB, 1 dB gain and better than 10 dB return loss across the UNII band. The HMC320MS8G & HMC320MS8GE also feature an adaptive baising that allows the user to select the optimal P1dB performance for their system using an external set resistor on the RES pin. P1dB performance can be set between a range of +1 dBm to +13 dBm. The low cost LNA uses an 8-leaded MSOP ground base surface mount plastic package, which occupies less 2 than 14.8 mm .
