For More Information On This Product, Go to: www.freescale.com Features Freescale Semiconductor, Inc. 1 Features This circuit is developed using Motorola RF BiCMOS technology. With a transmit frequency of 18GHz, the Antenna Booster/Splitter allows high RF performance at low cost. The Antenna Booster/Splitter function boosts the antenna signal, then splits it into two (2) 75 Ohm outputs for the TV and auxiliary outputs. Main applications are for: * * * * Set-Top Box (STB) VCR tuner PIP TV Video games RF output of the STB or VCR is added to the boosted received antenna signal. The MC44BC380 has the following features: Freescale Semiconductor, Inc... * * * * * Frequency operation range (40MHz to 880MHz) Extremely low external component count Low power consumption (35mA typical) Balanced inputs for low distortion Balanced amplifiers for maximum isolation 2 MC44BC380 Technical Data For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc. Functional Description 2 Functional Description Figure 2 is a simplified block diagram, which shows the basic circuit functionality. The MC44BC380 has separate Vccs and a maximum grounding pattern to ensure high performance in terms of isolation and leakage. The MC44BC380 comes in an SO8 package and has a minimum pin count, which reduces cost and application board space. NOTE: A BALUN is required at the input to achieve the stated performance.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation, input and output voltages should be constrained to the ranges indicated in the Recommended Operating Conditions. aximum ratings are those values beyond which damage to the device may occur. For functional peration, voltage should be restricted to the Recommended Operating Condition.

Intermodulation frequencies are all frequency combinations coming from the two input carriers F1 and F2:F2-F1, 2*F1-F2, 2*F2-F1 and F1+F2, falling into the 40Mhz to 900Mhz range. Intermodulation (IMD) measurement is the difference (in dBc) between F1 or F2 level at the Output (VCRTU or TVOUT) and spurious level, for all the following cases: F1=50Mhz and F2=60Mhz F1=300Mhz and F2=310Mhz F1=600Mhz and F2=610Mhz F1=100Mhz and F2=110Mhz F1=400Mhz and F2=410Mhz F1=700Mhz and F2=710Mhz F1=200Mhz and F2=210Mhz F1=500Mhz and F2=510Mhz F1=800Mhz and F2=810Mhz F1 and F2 input levels are set to 90dBuV. Spurious specification is the worst case IMD measurement.

Decoupling capacitors C5 and C6 decrease coupling between TVOUT and VCRTU through the Vcc line (bonding and PCB coupling) and increase TVOUT to VCRTU isolation (see proposed PCB layout). Pull-ups to Vcc may be needed on TVOUT and VCRTU pins to improve spurious performance at low Vcc (1uH in series with 75). Resistive pull-ups can also be used to decrease gain and increase spurious performance. For example, 267Ohms reduces gain by about 1dB and increases IMD value by 2 to 6dB. Trade-off depends on application requirements. * * 6 MC44BC380 Technical Data For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc.
