Product Description
The EC1019B is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 2000 MHz, the EC1019B typically provides
18.5 dB of gain, +31 dBm Output IP3, and +19.5 dBm P1dB.
The EC1019B consists of Darlington pair amplifiers using
the high reliability InGaP/GaAs HBT process technology
and only requires DC-blocking capacitors, a bias resistor,
and an inductive RF choke for operation. The device is
ideal for wireless applications and is available in low-cost,
surface-mountable plastic lead-free/green/RoHS-compliant
SOT-89 packages. A SOT-86 version is also available as
the EC1019C. All devices are 100% RF and DC tested.
The broadband MMIC amplifier can be directly applied to
various current and next generation wireless technologies
such as GPRS, GSM, CDMA, and W-CDMA. In addition,
the EC1019B will work for other various applications
within the DC to 4 GHz frequency range such as CATV
and mobile wireless.
