A Hybrid equivalent is formed replace, in new designs, the standard CATV Hybrid when one input stage ACA0861 is cascaded with an amplifiers currently in use. The MMICs consist ACA0861 output stage between two transmission of two parallel amplifiers, each with 12 dB gain. line baluns. For low gain applications a single The Amplifiers are optimized for exceptionally low ACA0861 can be used between baluns, for higher distortion and noise figure while providing flat gain gain applications more than two ACA0861 can and excellent input and output return loss. There be cascaded between baluns. See ACA0861 are four differently specified amplifiers available: two application note for more information. input stages and two output stages. The ACA0861A and the ACA0861C are input stages and are specified at +34 dBmV flat output.

These parts can be used alone for low gain, output. These parts can be used alone for low gain, low output level applications or can be cascaded with high output level applications or can be cascaded with one of the ACA0861 output stages for higher gain one of the ACA0861 input stages for higher gain. The and output signal drive level. The ACA0861A is a low ACA0861B is a low power dissipation part designed power dissipation part designed to drive the ACA0861B as the output stage with an ACA0861A input stage. output stage. The ACA0861C is a slightly higher power The ACA0861D is a higher power dissipation part dissipation part and provides the needed distortion designed as the output stage with an ACA0861C parameters to drive the ACA0861D output stage. input stage. Cascaded, an ACA0861A and ACA0861B provide exceptional push-pull hybrid equivalent performance an ACA0861C and an ACA0861D cascaded provide exceptional power doubling hybrid equivalent performance. 1 GND GND 16 N/C VA 2 15 RF INA RFOUTA 3 14 GND GND 4 13 GND GND 5 12 RF INB RFOUTB 6 11 I ADJ V B 7 10 GND GND 8 9 figure 2: Pin Out Table 1: Pin Description PIN NAME DESCRIPTION PIN NAME DESCRIPTION 1 GND Ground 9 GND Ground 2 N/C No Connection 10 VB Supply for Amplifier B 3 RFINA Input to Amplifier A 11 RFOUTB Output from Amplifier B 4 GND Ground 12 GND Ground 5 GND Ground 13 GND Ground 6 RFINB Input to Amplifier B 14 RFOUTA Output from Amplifier A 7 IADJ Current Adjust 15 VA Supply for Amplifier A 8 GND Ground 16 GND Ground Data Sheet - Rev 2.3 2 09/2008
