ALM-1106 GPS Low Noise amplifier with Variable bias current and Shutdown function Data Sheet Description Features Avago Technologies’s ALM-1106 is a LNA designed for GPS/ISM/Wimax applications in the (0.9-3.5)GHz frequency range. The LNA uses Agilent Technologies’s proprietary GaAs Enhancement-mode pHEMT process to achieve high gain operation with very low noise figures and high linearity. Noise figure distribution is very tightly controlled. Gain and supply current are guaranteed parameters. A CMOS compatible shutdown pin is included to turn the LNA off and provide a variable bias. • Advanced GaAs E-pHEMT The ALM-1106 LNA is useable down to 1V operation. It achieves low noise figures and high gain even at 1V, making it suitable for use in critical low power GPS/ISM band applications. • Adjustable bias current via one single external resistor/voltage • High Gain : 14.3 dB typ • Low component count • High IIP3 and IP1dB • Wide Supply Voltage: 1V to 3.6V • Shutdown current : < 0.1uA • CMOS compatible shutdown pin (VSD) current @ 2.85V : 90uA • Small Footprint: 2x2mm2 • Low Profile: 1.1mm typ • Ext matching for non-GPS freq band operation Simplified Schmatic VSD • Low Noise: 0.8 dB typ VDD Specifications (25 deg): At 1.575GHz, 2.85V 8mA (Typ) • Gain = 14.3 dB (Typ) BIAS • NF = 0.8 dB (Typ) • IIP3 = 4.7 dBm (Typ) RF_IN C C1 Amplifier2 AMP1 Surface Mount 2.0 x 2.0 x 1.1 mm3 C C2 RF_OUT • IP1dB = 1.8 dBm (Typ) • S11 = -11.8 dB (Typ) Pin 6 O AY WW • S22 = -12.4 dB (Typ) Pin Configuration Pin 5 Pin 1 GND Pin 2 S21 = 12.3dB NF = 1.0dB Pin 3 Pin 4 Bottom View Note: Package marking provides Orientation and identification “A” = Product Code “Y” = Year “WW” = Work Week Typical performance @ 1.0V supply LNA I/O’s : 1.

Demoboard schematic 4 C C1 Amplifier2 AMP1 C C2 Notes • L1 and L2 form the input matching network. The LNA module has a integrated coupling and DC-blocking capacitors at the input and output. Best noise performance is obtained using high-Q wirewound inductors. This circuit demonstrates that low noise figures are obtainable with standard 0402 chip inductors. Replacing L1, L2 and L3 with highQ wirewound inductors (eg. Cilcraft 0402CS series) will yield 0.1dB lower NF and 0.6dB higher Gain. • L3 is an output matching inductor. • C5 is a RF bypass capacitor. • PRL1 is a network that isolates the measurement demoboard from external disturbances. C3 and C4 mitigates the effect of external noise pickup on the VSD and VDD lines. These components are not required in actual operation. • Bias control is achieved by either varying the VSD voltage without R1 or fixing the VSD voltage to VDD and varying R1. Typical value for R1 is 18k Ohm for 8mA total current at VDD=+2.85V. • Higher gain and IP3 performance can be obtained by increasing the supply current. This can be achieved by reducing the value for R1 to obtain desired current. • For low voltage operation such as 1.5V or 1.0V, the R1 may be omitted and VSD connected directly to the supply pins.
