| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MRFIC1808/D The MRFIC Line 1.9 GHz GaAs Low Noise Amplifier Designed primarily for use in wireless Personal Communication Systems (PCS) applications such as Digital European Cordless Telephone (DECT), Japan's Personal Handy System (PHS) and the emerging North American systems as a preamp for discrete or integrated downmixers. The MRFIC1808 is a two-stage low noise amplifier in a low-cost SO-8 package. The amplifier can be matched to optimize gain or noise figure with simple off-chip input matching. The design employs a novel stacked MESFET design which reuses bias current for the highest gain at minimal current. A CMOS compatible RECEIVE ENABLE pin allows for very low standby current while the system is in transmit mode. * Usable Frequency Range = 1.7 to 2.1 GHz * 19 dB Typ Gain * 1.6 dB Typ Noise Figure * Simple Off-chip Matching for Maximum Gain/Noise Figure Flexibility * High Reverse Isolation = -34 dB (Typ) * Low Power Consumption = 13 mW (Typ) * Single Bias Supply = 2.7 to 4.5 Volts * Low Standby Current = 8 A (Typ) * Low Cost Surface Mount Plastic Package * Order MRFIC1808R2 forTape and Reel. R2 Suffix = 2,500 Units per 16 mm, 13 inch Reel. * Device Marking = M1808 1.9 GHz GaAs LOW NOISE AMPLIFIER MRFIC1808 CASE 751-05 (SO-8) VDD1 1 8 RX ENABLE N/C 2 7 GND RF OUT 3 6 RF IN LNA CAP 4 5 GND Pin Connections and Functional Block Diagram REV 1 (c)MOTOROLA RF DEVICE DATA Motorola, Inc. 1997 MRFIC1808 1 MAXIMUM RATINGS (TA = 25C unless otherwise noted) Rating Supply Voltage RF Input Power Enable Voltage Storage Temperature Range Operating Ambient Temperature Symbol VDD PRF RX ENABLE Tstg TA Limit 5.5 3 5.5 - 65 to +150 - 30 to +85 Unit Vdc dBm Vdc C C RECOMMENDED OPERATING RANGES Parameter RF Frequency Supply Voltage RX Enable Voltage, ON RX Enable Voltage, OFF Symbol fRF VDD RX ENABLE RX ENABLE Value 1.7 to 2.1 2.7 to 4.5 2.7 to VDD 0 to 0.2 Unit GHz Vdc Vdc Vdc ELECTRICAL CHARACTERISTICS (VDD = 3 V, TA = 25C, RF = 1.9 GHz, RX ENABLE = 3 V, Tested in Circuit Shown in Figure 1) Characteristic RF Gain SSB Noise Figure RF Output 3rd Order Intercept Point Output 1 dB Gain Compression Reverse Isolation (s12) Input Return Loss Output Return Loss Supply Current RX Mode Supply Current Standby Mode (RX ENABLE = 0 V) Min 16.0 -- -- - 3.0 -- -- -- -- -- Typ 19 1.6 13 1 -34 -12 -15 4.2 8 Max -- -- -- -- -- -- -- 6.5 25 Unit dB dB dBm dBm dB dB dB mA mA VDD C4 1 8 RX ENABLE 2 7 L1 RF OUT 3 6 C2 C3 RF IN 4 C1 5 C1 C2 C3, C4 L1 2 pF 1.8 pF 22 pF 5.6 nH Figure 1.
