GENERAL DESCRIPTION

The HMC8414 is a low noise wideband amplifier with a bypass

switch that operates from 0.1 GHz to 10 GHz. The integrated

bypass switch enables high dynamic range systems with large

receive path signal variation. In the bypass path, typical insertion

loss and input third-order intercept (IIP3) are 1.5 dB and 49.4 dBm,

respectively.

The HMC8414 features inputs and outputs that are internally

matched to 50 Ω over the full operating range of the device. The

single positive supply voltage can range from 3 V to 6 V. The bias

current is set by a resistor connected between the RBIAS pin and

VDD pins (RFOUT/VDD1 and VDD2), and can be varied around its

nominal value of 90 mA.

The HMC8414 is fabricated on a gallium arsenide (GaAs), pseudo-

morphic high electron mobility transistor (pHEMT) process. It is

housed in an RoHS-compliant, 3 mm × 3 mm, LFCSP package and

is specified for operation from −40°C to +85°C.
