Se +H. Frequency Accuracy Range (GHz) 0.8-2.3 + 0.3 dB or 2.0% MONOTONICITY: 0.8 to 2.3 GHz 3rd ORDER INTERMODULATION (IM3): -55 dBm typical, measured with two +10 dBm tones @ 869 MHz (f1) and 894 MHz (f2), the IM3 frequeny being 847 MHz (2f1-f2). IP3 (input) = +41.5 dBm The input IP3 is derived from the following relationship: IP3 = 3(Pin-a)-IM3 + a 2 where o = the insertion loss (dB) at the IM3 frequency; Pin=single tone input power (dBm). POWER RATING: +24 dBm maximum +30 dBm (1 dB compression point) SWITCHING TIME: 2 psec. maximum OPERATING VOLTAGE: +5 V @ 160 mA for 6 cell/200 mA for 8 cell typical TEMPERATURE RANGE (Operating): 0C to +70C TEMPERATURE COEFFICIENT: < 0.002 dB/dB/C CONNECTORS: SMA female connectors per MIL-STD-348 interface dimensions - mate nondestructively with MIL-C- 39012 connectors. CONTROL CONNECTOR: AMP-Latch 10 pin ribbon cable connector mates with AMP P/N 746285-1 (supplied with each unit) WEIGHT: 4216-X 175g (6.1 02) 4218-X 215g (7.502) CONTROL CONFIGURATION: Units are supplied with a built-in TTL interface. Each unit is supplied with a mating 10 pin connector (Amp 746285-1). Refer to Physical Dimensions for mating connector pin/wiring details. Two wires are specified for supply voltage and ground. The remaining wires will accept TTL control signals to activate or de-activate a particular attenuation cell. A TTL high will energize a cell to the high attenuation state, whereas a TTL low will maintain a cell in its zero attenuation state. 5305 Spectrum Drive, Frederick, MD 21703-7362 * TEL: 301-846-9222, 800-638-2048 Fax: 301-846-9116 4/24/99 web: www.weinschel.com email: sales@weinschel.com PHYSICAL DIMENSIONS: Models 4216 & 4218: 11.93 wae a 9.14 (47) (136) 2,29 23.29 (09) oan 8 @ 3) @) 41,85 46.48 yh (1,648) ap 1.63) 2 /t@ @ @ i SMA FEMALE / bY TYP 2 PLCS - "B 15.00 (63) 2-56 UNC-28 X 3.05 (.12) DP 2 PLCS TYP BOTH SIDES a Cc PIN 2 PINIO 5,59 \ / { Loft of ot 28 PIN 1 8.71 (343) 17 . 14 "D (675) 6-32 UNC-2B X 4.83 (.19) DP TYP 2 PLCS BOTH SIDES Control Connector J3 Pin Locations: Model No. A B Cc D TTL Conn 4216-63 | 4218-63.75-1| 4218-127 4216-X 71.12 (2.80) | 94.74 (2.50) | 47.49 (1.87) _|63.50 (2.50) PIN No. (J3) |_dB (Cell) dB (Cell) | dB (Cell) 4218-X 99.56 (3.92) | 123.19 (4.85) | 61.72 (2.43) |88.90 (3.50) 1 1 0.25 1 2 2 0.50 2 NOTE: All dimensions are given in mm (inches) and are : . gs 3 4 1 4 maximum, unless otherwise specified. 4 8 2 8 5 16 4 16 6 32 8 32 7 NC 16 32* 8 NC 32 32* 9 +5V +5V +5V 10 COM COM COM NC = Not Connected *Pins 7 and 8 combined to create 64 dB cell.
