| ACA0861 -- A, B, C, D 750/860 MHz CATV LINE AMPLIFIER MMIC Advanced Product Information Rev 2 DESCRIPTION The ACA0861 family of surface mount monolithic GaAs RF Linear Amplifiers has been developed to replace, in new designs, the standard CATV Hybrid amplifiers currently in use. The MMICs consist of two parallel amplifiers, each with 12 dB gain. The Amplifiers are optimized for exceptionally low distortion and noise figure while providing flat gain and excellent input and output return loss. There are four differently specified Amplifiers available, two input stages and two output stages. The ACA0861A and the ACA0861C are input stages and are specified at +34 dBmV flat output. The ACA0861B and ACA0861D are output stages and are specified at +44 dBmV flat output. A Hybrid equivalent is formed when one input stage ACA0861 is cascaded with an ACA0861 output stage between two transmission line baluns. For low gain applications a single ACA0861 can be used between baluns, for higher gain applications more than two ACA0861 can be cascaded between baluns. See ACA0861 application note for more information.

C/W C A INPUT STAGES The ACA0861A and the ACA0861C are designed as input stages and are specified at +34 dBmV flat output. These parts can be used alone for low gain, low output level applications or can be cascaded with one of the ACA0861 output stages for higher gain and output signal drive level. The ACA0861A is a low power dissipation part designed to drive the ACA0861B output stage. The ACA0861C is a slightly higher power dissipation part and provides the needed distortion parameters to drive the ACA0861D output stage. OUTPUT STAGES The ACA0861B and ACA0861D are designed as output stages and are specified at + 44 dBmV flat output. These parts can be used alone for low gain, high output level applications or can be cascaded with one of the ACA0861 input stages for higher gain. The ACA0861B is a low power dissipation part designed as the output stage with an ACA0861A input stage. The ACA0861D is a higher power dissipation part designed as the output stage with an ACA0861C input stage. An ACA0861A and ACA0861B cascaded provide exceptional push-pull hybrid equivalent performance, an ACA0861C and ACA0861D cascaded provide exceptional power doubling hybrid equivalent performance (see Figure 2).

Balun effects deimbedded from measurement. Measured with a balun on input and output of the device. See Figure 1 for test setup. All parts measured with 110 channel flat input. Parts A & C measured at +34 dBmV output. Parts B & D measured at 44 dBmV output (per channel). A fixed resistor is needed for parts A through C, part D does not need an external resistor. These resistors set the devices' current draw. Bias voltage is 12 VDC.
