Functional Diagram
General Description
The HmC668lp3(e) is a versatile, high dynamic range GaAs mmiC low Noise Amplifier that integrates a low loss lNA bypass mode on the iC. The amplifier is ideal for receivers and lNA modules operating between 0.7 and 1.2 GHz and provides 0.9 dB noise figure, 16 dB of gain and +33 dBm ip3 from a single supply of +5V @ 57mA. input and output return losses are excellent and no external matching components are required. A single control line is used to switch between lNA mode and a low loss bypass mode. The failsafe topology enables the lNA bypass path, when no DC power is available. The HmC668lp3(e) offers improved noise figure versus the previously released HmC373lp3(e).

The circuit board used in the application should use rf circuit design techniques. signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
