HMC320MS8G

HMC320MS8G / 320MS8GE v03.0308 GaAs MMIC LOW NOISE AMPLIFIER , 5 - 6 GHz 8 LOW NOISE AMPLIFIERS - SMT Typical Applications The HMC320MS8G(E) is ideal for: • UNII • HiperLAN Features Selectable Functionality: LNA, Driver, or LO Buffer Amp Adjustable Input IP3 Up to +10 dBm +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 fixed gain Low Noise Amplifiers (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 than 14.8 mm2.

The table below contains the HMC320MS8G RF performance as a function of various VSET and RBIAS settings. It will be necessary for the VSET voltage source to provide 100uA of current to the amplifier. The Idd and Vdd quiescent performance will not change as a function of changing the VSET voltage. 8 LOW NOISE AMPLIFIERS - SMT 8 - 23 RF Performance at 5.8 GHz (Vdd = +3V) VSET (VDC) 0 3 3 3 RBIAS Resistor Between Pin 3 and GND (Ohms) 174 22 7 GND (No Resistor) Idd (mA) 7 25 40 60 Output P1dB (dBm) 1.0 9.0 13.0 14.0 Output Return Loss (dB) 16.0 12.0 15.0 15.0 Applying the adaptive biasing A dynamically controlled bias can be implemented with this design. A typical application wil include sensing an RF signal level and then adjusting the VSET. The bias adjustment can be accomplished by either analog or digitals means, after the RF signal has been detected and translated to a DC voltage using external power detection circuitry.
