DESCRIPTION
A double balanced approach was chosen to assure good isolation characteristics and a minimum of spurious products. No output transformer or balun is required. FEATURES
D Supply voltage range: 2.7 to 5.5 V D Single-ended output, no balun required D Single-ended input for RF and LO D Exellent isolation characteristics D Power down mode D IP3 and compression point programmable D 2.5-GHz operating frequency D SO-8 package Benefits D Reduced system costs due to few external component (no balun) requirements D Standard independent product D 3-V operation reduces the battery count and saves space Block Diagram VS 2 RFi 3 P R1 VH VH VR Voltage regulator PD 8 R2 IFo 5 So 4 LO i 7 GND 6 VS 1 93 7811 e Rev.
