F2923 Datasheet Constant Impedance KK SP2T RF Switch 300 kHz to 8000 MHz ZZ GENERAL DESCRIPTION FEATURES The F2923 is a low insertion loss 50 SP2T absorptive Constant Impedance KK during transition ZZ RF Switch designed for a multitude of wireless and Very low insertion loss: 0.48 dB 2 GHz other RF applications. This device covers a broad High Input IP3: 66 dB 2 GHz frequency range from 300 kHz to 8000 MHz. In RF1/RF2 to RF Com Isolation: 74 dB 2 GHz addition to providing low insertion loss, industry 1-pin or 2-pin device control option leading isolation at 2 GHz and excellent linearity, the Low DC current: 127 A using 3.3 V logic F2923 also includes a patent pending constant Supply voltage: 3.3 V impedance (K ) feature. K minimizes LO pulling in Supports 1.8 V and 3.3 V control logic Z Z VCOs and reduces phase and amplitude variations in Extended temperature: -55 C to +105 C distribution networks. It is also ideal for dynamic 4 mm x 4 mm, 20-pin TQFN package switching/selection between two or more amplifiers Pin compatible with F2912 while avoiding damage to upstream/downstream sensitive devices such as PAs and ADCs. FUNCTIONAL BLOCK DIAGRAM The F2923 uses a single positive supply voltage of 3.3 V supporting three states using either 3.3 V or Mode CTL CTL Pins 1.8 V control logic. An added feature includes a ModeCTL pin allowing the user to control the device with either 1-pin or 2-pin control. COMPETITIVE ADVANTAGE 50 50 The F2923 provides constant impedance on all ports RF1 RF2 during transitions without compromising isolation, linearity, or insertion loss. 50 Constant impedance KK during switching transition ZZ VSWR RF Com port 1.4:1 vs. 9:1 for Standard Switch Insertion Loss = 0.48 dB* IIP3: +66 dBm* RF COM RF1/RF2 to RF COM Isolation = 74 dB* Extended temperature: -55 C to +105 C ORDERING INFORMATION Negative supply voltage not required Tape & Reel *2 GHz F2923NCGI8 APPLICATIONS Base Station 2G, 3G, 4G RF Product Line Green Portable Wireless Repeaters and E911 systems Digital Pre-Distortion Point to Point Infrastructure Public Safety Infrastructure WIMAX Receivers and Transmitters Military Systems, JTRS radios RFID handheld and portable readers Cable Infrastructure Wireless LAN Test / ATE Equipment F2923, Rev O 11/9/2015 1 F2923 ABSOLUTE MAXIMUM RATINGS Parameter / Condition Symbol Min Max Unit Vcc to GND Vcc -0.3 +3.9 V CTL1, CTL2 V -0.3 Vcc + 0.3 V CNTL ModeCTL to GND V -0.3 Vcc + 0.3 V MODE RF1, RF2, RF COM V -0.3 +0.3 V RF Maximum Junction Temperature T +140 C Jmax Storage Temperature Range T -65 +150 C ST Lead Temperature (soldering, 10s) T +260 C LEAD ESD Voltage HBM (Per JESD22-A114) V Class 2 ESDHBM ESD Voltage CDM (Per JESD22-C101) V Class III ESDCDM ABS MAX RF POWER AT 2 GHZ WITH TC = +85 C * RF1, RF2, RF COM (RF1 or RF2 is connected to RF COM, IL States) +33dBm RF1, RF2, RF COM (When port is internally terminated) +24dBm ABS MAX RF POWER AT 2 GHZ WITH TC = +105 C * RF1, RF2, RF COM (RF1 or RF2 is connected to RF COM, IL States) +33dBm RF1, RF2, RF COM (When port is internally terminated) +21dBm * Temperature of exposed paddle Stresses above those listed above may cause permanent damage to the device.
