| Ultra Low Noise pHEMT Dual Channel Amplifier, 1.710-1.910 GHz V 3.00 AM40-0023 Features n n n n n n n CR-5 0.7 dB Typical Noise Figure 14 dB Typical Gain DC Decoupled RF Input and Output Single Bias Configuration SMT Construction Dual Channels for Balanced Designs Unconditionally Stable--No External Matching Circuit required Description M/A-COM's AM40-0023 is a dual-channel, ultra low noise amplifier in a surface mount package. Very low noise figure is achieved by using discrete pHEMT devices combined with M/A-COM's glass technology. The AM40-0023 is designed specifically for use in DCS-1800 and PCS telecommunication applications where less than 1 dB noise figure is required. Absolute Maximum Ratings 1 Parameter Max Input Power 2 2 Absolute Maximum +15 dBm +10.0 V -55C to +125C -65C to +150C Operating Voltage Operating Temperature Storage Temperature 1. Operation of this device above any one of these parameters may cause permanent damage. 2. Ambient Temperature (TA) = +25C Electrical Specifications: Bias Conditions: +7V @ 20 mA Typical (each channel,) TA = +25C, Z0 = 50 Ohms Parameter Gain Gain Flatness Noise Figure VSWR Input VSWR Output 1 dB Compression Reverse Isolation Input Third Order Intercept Test Conditions PIN = -20 dBm PIN = -20 dBm -- PIN = -20 dBm PIN = -20 dBm Input Power -- -- Frequency 1.710-1.910 GHz 1.710-1.910 GHz 1.710-1.910 GHz 1.710-1.910 GHz 1.710-1.910 GHz 1.710-1.910 GHz 1.710-1.910 GHz 1.710-1.910 GHz Units dB dB dB Ratio Ratio dBm dB dBm Min. 11 -- -- -- -- -13 20 0 Typ. 14 1.0 0.7 2.0:1 2.0:1 -9 25 3 Max. -- 1.5 0.9 3.0:1 3.0:1 -- -- -- Ultra Low Noise pHEMT Dual Channel Amplifier, 1.710-1.910 GHz AM40-0023 V 3.00 Typical Performance Curves Input & Output Return Loss Gain vs. Frequency RF OUT 18 RF IN 0 Return Loss (dB) 16 -5 Gain (dB) 14 -10 12 -15 10 1700 1750 1800 1850 1900 1950 2000 -20 1700 1750 1800 1850 1900 1950 2000 Frequency (MHz) Frequency (MHz) Noise Figure vs. Frequency Functional Schematic (Top View) GND 1 1.0 Noise Figure (dB) 0.8 0.6 0.4 RF OUTB 2 10 RF OUTA VDDB 3 9 VDDA N/C 4 8 N/C 0.2 RF INB 5 7 RF INA 0.0 1700 1750 1800 1850 1900 1950 2000 6 Frequency (MHz) GND Ordering Information Part Number AM40-0023 Package CR-5 Specifications subject to change without notice. n North America: Tel.
