1 MHz to 2.7 GHz RF Gain Block Data Sheet AD8354 FEATURES FUNCTIONAL BLOCK DIAGRAM Fixed gain of 20 dB Operational frequency of 1 MHz to 2.7 GHz Linear output power up to 4 dBm BIAS AND VREF VPOS Input/output internally matched to 50 Ω Temperature and power supply stable INPT VOUT Noise figure: 4.2 dB Power supply: 3 V or 5 V APPLICATIONS COM1 AD8354 COM2 02722-001 Figure 1. VCO buffers General Tx/Rx amplification Power amplifier predrivers Low power antenna drivers GENERAL DESCRIPTION The AD8354 is a broadband, fixed-gain, linear amplifier that The noise figure is 4.2 dB at 900 MHz. The reverse isolation operates at frequencies from 1 MHz up to 2.7 GHz. It is (S ) is −33 dB at 900 MHz. 12 intended for use in a wide variety of wireless devices, including The AD8354 can also operate with a 5 V power supply; in cellular, broadband, CATV, and LMDS/MMDS applications. which case, no external inductor is required. Under these By taking advantage of ADI’s high performance, complementary Si conditions, the AD8354 delivers 4.88 dBm with 20 dB of gain bipolar process, these gain blocks provide excellent stability at 900 MHz. The dc supply current is 26 mA. At 900 MHz, the over process, temperature, and power supply. This amplifier is OIP3 is greater than 19 dBm; at 2.7 GHz, the OIP3 is 15 dBm. single-ended and internally matched to 50 Ω with a return loss The noise figure is 4.4 dB at 900 MHz. The reverse isolation of greater than 10 dB over the full operating frequency range. (S ) is −33 dB. 12 The AD8354 provides linear output power of nearly 4.3 dBm The AD8354 is fabricated on ADI’s proprietary, high performance, with 20 dB of gain at 900 MHz when biased at 3 V and an 25 GHz, Si complementary, bipolar IC process. The AD8354 is external RF choke is connected between the power supply and available in a chip scale package that uses an exposed paddle for the output pin. The dc supply current is 24 mA. At 900 MHz, excellent thermal impedance and low impedance electrical the output third-order intercept (OIP3) is greater than 18 dBm; connection to ground. It operates over a −40°C to +85°C at 2.7 GHz, the OIP3 is 14 dBm. temperature range, and an evaluation board is also available. Rev.

Data Sheet AD8354 THEORY OF OPERATION The AD8354 is a 2-stage, feedback amplifier employing both It is critical to supply very low inductance ground connections shunt-series and shunt-shunt feedback. The first stage is to the ground pins (Pin 1, Pin 4, Pin 5, and Pin 8) as well as to degenerated and resistively loaded and provides approximately the backside exposed paddle. This ensures stable operation. 10 dB of gain. The second stage is a PNP-NPN Darlington The AD8354 is designed to operate over a wide supply voltage output stage, which provides another 10 dB of gain. Series- range, from 2.7 V to 5.5 V. The output of the part, VOUT, is shunt feedback from the emitter of the output transistor sets the taken directly from the collector of the output amplifier stage. input impedance to 50 Ω over a broad frequency range. Shunt- This node is internally biased to approximately 3.2 V when the shunt feedback from the amplifier output to the input of the supply voltage is 5 V. Consequently, a dc blocking capacitor Darlington stage helps to set the output impedance to 50 Ω. The should be connected between the output pin, VOUT, and the amplifier can be operated from a 3 V supply by adding a choke load that it drives. The value of this capacitor is not critical, but inductor from the amplifier output to VPOS. Without this it should be 100 pF or larger. choke inductor, operation from a 5 V supply is also possible. BASIC CONNECTIONS When the supply voltage is 3 V, it is recommended that an external RF choke be connected between the supply voltage The AD8354 RF gain block is a fixed gain amplifier with single- and the output pin, VOUT. This increases the dc voltage applied ended input and output ports whose impedances are nominally to the collector of the output amplifier stage, which improves equal to 50 Ω over the frequency range 1 MHz to 2.7 GHz. performance of the AD8354 to be very similar to the performance Consequently, it can be directly inserted into a 50 Ω system produced when 5 V is used for the supply voltage. The inductance with no impedance matching circuitry required. The input and of the RF choke should be approximately 100 nH, and care output impedances are sufficiently stable vs. variations in should be taken to ensure that the lowest series self-resonant temperature and supply voltage that no impedance matching frequency of this choke is well above the maximum frequency compensation is required.
