Typical Applications The HMCMSG(E) is ideal for: UNII HiperLAN Functional Diagram v. Electrical Specifications, T A = + C, Vdd = +V HMCMSG / MSGE Features General Description Selectable Functionality: LNA, Driver, or LO Buffer Amp Adjustable Input IP Up to +1 dbm +V Operation Ultra Small Lead MSOP: 1. x 1. x 1 mm The HMCMSG & HMCMSGE are low cost C-band fi xed gain Low Noise Amplifi ers (LNA). The HMCMSG & HMCMSGE operate using a single positive supply that can be set between +V and +V. With +V bias, the LNA provides a noise fi gure of. db, 1 db gain and better than 1 db return loss across the UNII band. The HMCMSG & HMCMSGE 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 +1 dbm. The low cost LNA uses an -leaded MSOP ground base surface mount plastic package, which occupies less than 1. mm.

Adaptive Biasing Optimizing P1dB Performance The bias level may be changed to adjust the P1dB and return loss performance. The table below contains the HMC- MSG RF performance as a function of various VSET and RBIAS settings. It will be necessary for the VSET voltage source to provide 1uA of current to the amplifi er. The Idd and Vdd quiescent performance will not change as a function of changing the VSET voltage. RF Performance at. GHz (Vdd = +V) VSET (VDC) 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.
